FindPkgConfig: ignore whitespace separators in version check

The regex used to split up the version if it contains an operator fails
if the string contains whitespaces. Resulting in an extra whitespace
after the package name and before the package version leading to
breakage in pkgconf and thus webkit-gtk.
