ci: Specify -Wno-overlength-strings on macOS

Browse Source 
This disables the following warning, which was causing CI failures on
macOS when building the libpcre2 subproject:
```
../subprojects/pcre2-10.40/src/pcre2_error.c:66:3: error: string literal of length 4380 exceeds maximum length 4095 that ISO C99 compilers are required to support [-Werror,-Woverlength-strings]
```

We don’t want to explicitly rely on using overlength strings in GLib,
which is why this change is a `CFLAGS` in the CI configuration, rather
than setting a project-level argument in `meson.build`.
