pcre: use UTF only when available in the library
Before this change, if linked with a PCRE library without unicode
any invocations of grep when using a UTF locale will error with:
grep: this version of PCRE2 does not have Unicode support
* src/pcresearch.c: Check whether Unicode was compiled in.
* tests/pcre-utf8-w: Add check to skip test.
* tests/pcre-utf8: Update check.
