When a SHA-1 hash of a specific commit is used as a tag, the regex
shenanigans later in the script can (and will) corrupt it in certain
cases.
e.g.:
$ perl -e '
$tag="6e8cd92261577230daa1098f7e05ec198c3c4281";
$tag=~s/[^0-9]+?([0-9]+)/$1/;
print("$tag\n");
'
68cd92261577230daa1098f7e05ec198c3c4281
(Notice the missing 'e')
Let's fix this by limiting the regex's scope to a non-SHA-1 tags only.
In the module-build-service, we have pieces of dracut provided by different
modules ("base-runtime" provides most functionality, but we need
dracut-network in "installer". Since these two modules build with separate
dist-tags, we need to reduce this strict requirement to ignore the dist-tag.
