libsupport: fix sort_r.h to work on FreeBSD 14

FreeBSD 14 has changed the definition of qsort_r to align it with the POSIX, but it did this with a #define. So when sort_r.h tries to provide a function prototype, surround the function name with parenthesis so it doesn't get expanded by FreeBSD's #define. Signed-off-by: Theodore Ts'o <[email protected]>
