grep: improve PCRE2 version output
* src/grep.c: No need to include pcre2.h.
(main) [HAVE_LIBPCRE]: Call Pprint_version instead of
doing it ourselves.
* src/pcresearch.c (Pprint_version): New function.
It also checks belatedly for buffer overflow, and
says "grep -P uses PCRE2" instead of "Built with PCRE".
* tests/version-pcre: Adjust test to match.
