use enhanced basic regular expressions on macOS
When 1819ad3 (grep: fix multibyte regex handling under macOS, 2022-08-26) started to use the native regex library instead of Git's own (compat/regex/), it lost support for alternation in basic regular expressions. Bring it back by enabling the flag REG_ENHANCED on macOS when compiling basic regular expressions.
