SrHtApi.php: fix uploading subpackages
Do not hardcode the package name in the glob of apks to be uploaded. Instead, upload everything in work/packages/arch/*.apk.
This should fix uploading subpackages, which do not start with the package name, such as the "musl-dev-aarch64" subpackage of "musl-aarch64". The currently broken behavior can be seen in 1, and causes gcc-aarch64 and similar package builds to fail, because they miss musl-dev-aarch64 2.
Using *.apk is safe, since we started using 'pmbootstrap build --no-depends' recently. So we are sure that we only build the package we are intending to build, and therefore only apks for that will be produced and catched by that glob.
@MartijnBraam: does this make sense? And can you re-trigger the "musl-*" packages after this is merged (or should I re-trigger them with a pkgrel bump? won't work, since we're keeping pkgver and pkgrel in sync with alpine's musl package)
