lsfd: fix bsearch macro usage with glibc C23

C23 requires bsearch to be a const preserving macro, build now fails
with

../lsfd-cmd/lsfd.c:1879:75: error: macro ‘bsearch’ passed 6 arguments, but takes just 5
 1879 |                                     nfds, sizeof(struct pollfd), pollfdcmp))

  add parenthesis around expression to fix it.
