The current logic scans qemu.git/subprojects/ from *.wrap files to
determine whether or not to include the associated directories in the
release tarballs. However, the script assumes that it is being run from
the top-level of the source directory, which may not always be the case.
In particular, when generating releases via, e.g.:

  make qemu-9.2.1.tar.xz

the $CWD will either be an arbitrary external build directory, or
qemu.git/build, and the exclusions will not be processed as expected.
Fix this by using the $src parameter passed to the script as the root
directory for the various subproject/ paths referenced by this logic.

Also, the error case at the beginning of the subproject_dir() will not
result in the error message being printed, and will instead produce an
error message about "error" not being a valid command. Fix this by using
basic shell commands.

It would be best if this change is applied to master as a quick fix
(it does not affect anything in master at all, including CI), so we
can resolve an issue on download.qemu.org (wrong 9.2.1 tarballs).

BTW, I always invoked ./scripts/make-release directly, I didn't know
there's a make rule for it.  And I always did this by staying in the
qemu/master worktree :)

Thanks!

Thanks for including this patch in your pull request. It's running
through CI right now.
