set update to ignore alpha/beta/dev/rc versions

[tornaria]

I looked at all the updates which correspond to alpha/beta/dev/rc versions as follows:

$ wget -c http://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt
$ cat void-updates.txt | grep -- '-> [0-9.-]*[^0-9. -]' | awk '{print $1}' | sort -u | xargs -n1 ./xbps-src update-check > todo.txt
$ wc -l todo.txt
362 todo.txt

After the patch, the same thing gives 195 updates, can diff before/after to see the change. There are a few packages which I didn't look into (e.g. debian version suffixes).

Most is *a[0-9] *b[0-9] *rc[0-9] *.dev[0-9], especially for python packages, I wonder if that should be default, but then some packages use versions that match some of those.

No file other than srcpckgs/*/update is touched by this commit.

@paper42 I added a commit fixing the gnome pattern (e.g. fixes gtk4), but I can drop it from this PR if you prefer.

I think we should test that a bit more, so let's split it to a separate PR.
