Makefile requires the user to provide the USE_LIBPCRE2 flag to
enable this dependency, but meson has it enabled by default,
which can be problematic, at least in macOS.
While a popular option and matching what was done by cmake
(which itself reflects what is preferred by Git for Windows)
could result in a broken build or linking with the wrong PCRE2
library.
While not git's fault, macOS provides a PCRE2 library in base
that is not usable (even if it would pass the test) and not
configured properly, as it installs a pkgconf module that
points to a non existent pcre2.h header in /usr/local/include.
Change the default to off, and let the user enable it once a
proper dependency is installed or meson instructed to fallback to
the wrap.
