In commit 91b72cc386ca03241791748da5da2b150c724ace support was added for
linting depends/etc. to ensure they contain only valid dependency
specifiers. However it did not properly take into account the
possibility of dependencies linked to a specific pkgrel or epoch, which
promptly failed to build because "-" and ":" is not allowed in a pkgver.

pkgrel is something supported by pacman and useful for e.g. split packages
which cannot be mismatched even if the pkgver is the same. Fix by
removing an optional suffixed "-$decimal" when checking for a valid
pkgver.

epoch is kind of difficult to do without :D so likewise fix by removing
an optional prefixed "$integer:"

v3: ugh, that wasn't right at all. names must be greedily trimmed,
because otherwise, given >=, we end up with name="foo>"
