Really support architectures other than amd64

[9at8]

I was trying to run this on my raspberry pi 4 using docker-compose.

This is the error that I get:

standard_init_linux.go:228: exec user process caused: exec format error

Based on some initial searching, it looks like it's because of an incorrect architecture of the image.

I used the docker manifest to find out what architectures this image supports:

`docker manifest inspect --verbose bytemark/webdav:latest`

``` ❯ docker manifest inspect --verbose bytemark/webdav:latest { "Ref": "docker.io/bytemark/webdav:latest", "Descriptor": { "mediaType": "application/vnd.docker.distribution.manifest.v2+json", "digest": "sha256:21eed0df1238d17766080425f9ef46da2c1130e3e3aa9eaf36794d2a72e7c616", "size": 1989, "platform": { "architecture": "amd64", "os": "linux" } }, "SchemaV2Manifest": { "schemaVersion": 2, "mediaType": "application/vnd.docker.distribution.manifest.v2+json", "config": { "mediaType": "application/vnd.docker.container.image.v1+json", "size": 9327, "digest": "sha256:c124350447bb537f4d4c5dc11cdaba36514a6bfc87849369e3f1f1fac99288d9" }, "layers": [ { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 2206931, "digest": "sha256:4fe2ade4980c2dda4fc95858ebb981489baec8c1e4bd282ab1c3560be8ff9bde" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 1250, "digest": "sha256:42101a4e4c4e87a675d887d6ae4d470a2ac9e1a944641f6be9e6deaa94d9bd3e" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 147, "digest": "sha256:73eadb9961ffcaea4b38b93d524510b20b1f2ca02632019b4d8f03db3a7a380c" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 28322442, "digest": "sha256:830983fb5ec2bff731ddde5c140ed82347f121b2db486d769a8679bcf97d3d64" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 293, "digest": "sha256:78fb51bbfc274598464d48a6e867d19363e2deda93e1db1c26b5bd00e2036598" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 1168, "digest": "sha256:a39c1a5fbc6f6fef2bf9ea8168fa8da44b4c2505f3e59692cfd717cd570d5636" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 1660081, "digest": "sha256:1f4c3ea2abf9e947059e2ca985bce633257a491cf03520cfdea8deed15bb18c2" }, { "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip", "size": 1596, "digest": "sha256:ce5492a1029f017d4dc9b768e62427913e2ffa0ef674e2c604da3e5ebfdc17f0" } ] } } ```

Based on the README, this image should support all architectures supported by httpd.

`docker manifest inspect --verbose httpd:latest`
