common/xbps-src/shutils/update_check.sh: tweak url and rx for git.sr.ht
https://github.com/void-linux/void-packages/pull/40372

Description:
#### Testing the changes
- I tested the changes in this PR: **YES**
- `grep -lr --include template git.sr.ht srcpkgs/ | cut -d/ -f2 | xargs -n1 ./xbps-src update-check`

A few packages with `git.sr.ht` upstream, such as [imv](https://git.sr.ht/~exec64/imv/refs), uses commit hash to name their release tarballs instead of a version string. These packages (imv, mymcplus, pc & dotool) all report `NO VERSION` to the update checker in current master.

With this change, the custom update file of `clickclack` breaks as it mitigated the issue mentioned above in a different way. But it's now redundant and reports updates correctly without a separate update file. `wlopm` (maintained by me) also had a redundant update file so I removed it too.
