switch UI: Only build ovs-switchui if PCRE 7.2 or later is available.

The PCRE_INFO_OKPARTIAL feature used by ovs-switchui was only introduced
in PCRE 7.2, so we need to check for that version or later, instead of
just for PCRE.

Thanks to Ian Campbell <Ian.Campbell@citrix.com> for reporting the problem.
