[LTP] [PATCH] m4: remove useless ltp-securebits.m4

[Yang Xu]

Since commit fe9d9218c, we have detected linux/securebits.h in
confiure.ac. one place used the HAVE_SECUREBITS(ltp-securebits.m4 
defined), it only controls compile. kernel/security/securebits/
check_keepcaps.c has HAVE_LINUX_SECUREBITS_H check in internal, 
so removing it is safe.
