Use existence of type as #ifdef condition rather than FreeBSD-specific
version check, as suggested by Patrick Welche.

Also handle the signed (CTLTYPE_S64) case identically to the unsigned
(CTLTYPE_U64) case, per later patches in the FreeBSD ports tree
(emulators/qemu-devel/files/patch-z-arm-bsd-user-001).

Applied to trivial-patches tree (8e4125147a8bc4da2c1e8eced722ebe31bafc19e),
