Update PCRE tests to fix case confusion (Closes: #1095286)

Update PCRE tests to fix case confusion (Closes: #1095286)

MariaDB RLIKE is case-insensitive; in perl the Unicode character
property tests \p{Lu} and \p{Ll} are equivalent to \p{L&} in
case-insensitive matches. So remove those tests (since there is
already the \p{L&} test).

This fixes a FTBFS with PCRE2 10.45 which fixed its handling of Ll Lt
and Lu under case-insensitive matching to match perl's behaviour.

Example of failure seen in MTR:

    main.func_regexp_pcre                    w4 [ fail ]
