* meson.build: Fix build for other UNIX systems (e.g., FreeBSD).
Without this change the build of `unix/ftsystem.c` fails because the
`ftconfig.h` header that defines macros such as `HAVE_UNISTD_H` and
`HAVE_FCNTL_H` is only being generated for Linux, macOS, and Cygwin
systems:
```
.../builds/unix/ftsystem.c:258:32: error:
use of undeclared identifier 'O_RDONLY'
file = open( filepathname, O_RDONLY );
```
Instead of hardcoding a list of operating systems for this check,
update the logic that decides whether to build the file and set a
boolean flag that can be checked instead.
