Remove nested always-false ifdef for HPUX and FREEBSD

* include/private/gcconfig.h (USE_HPUX_FIXED_STACKBOTTOM): Add missing
dot in comment.
* os_dep.c (old_bus_act, GC_set_and_save_fault_handler,
GC_reset_fault_handler): Remove false ifdef check for HPUX and FREEBSD
inside ifdef for SUNOS5SIGS, IRIX5, OSF1, HURD, or NETBSD.
