Permission denied on temp dir deletion when extracting archive with read-only directory on GNU/Linux

[rominf]

Steps to reproduce

On GNU/Linux with zip installed:

$ cd /tmp
$ mkdir readonly_dir
$ touch readonly_dir/readonly_file
$ chmod 400 readonly_dir/readonly_file
$ chmod 500 readonly_dir/
$ zip archive.zip readonly_dir/ readonly_dir/readonly_file
adding: readonly_dir/ (stored 0%)
adding: readonly_dir/readonly_file (stored 0%)
$ echo -e 'import nimarchive\n\nextract("/tmp/archive.zip", "/tmp/output")' >/tmp/test_nimarchive.nim
$ nim run /tmp/test_nimarchive.nim

Proposed solution

Recursively add user write permissions to temporary dir.

Notes

• I've tested extraction with Ark, and it handles this well.
• This is not an artificial example. Have a look at Guix binary (https://ftp.gnu.org/gnu/guix/guix-binary-1.2.0.x86_64-linux.tar.xz).
