Make test-alpine work on ARM as well

[webmaster128]

To make this test work on ARM systems, we need to ensure a few things

• [x] The testing images $(ALPINE_TESTER) and alpine:3.xx all use the same architecture. This could be native, i.e. arm64.
• [ ] The library internal/api/libwasmvm_muslc.aarch64.a is moved to internal/api/libwasmvm_muslc.a at the start of the test to make // #cgo LDFLAGS: -Wl,-rpath,${SRCDIR} -L${SRCDIR} -lwasmvm_muslc work
  • [x] In order to do that without overriding the x86_64 build, the build output files should be libwasmvm_muslc.aarch64.a and libwasmvm_muslc.x86_64.a, similar to what we see in release-build-linux
  • [x] Builders version 0018 finished, deployed and used

The point

The library internal/api/libwasmvm_muslc.aarch64.a is moved to internal/api/libwasmvm_muslc.a at the start of the test to make // #cgo LDFLAGS: -Wl,-rpath,${SRCDIR} -L${SRCDIR} -lwasmvm_muslc work

is not needed anymore because muslc is now linked with an arch specific file name:
