When 1819ad327b (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.
