CHROMIUM: arch/arm: move secure_computing into trace; respect return code

(I will post this upstream after the 3.5 merge window)

There is very little difference in the TIF_SECCOMP and TIF_SYSCALL_TRACE
patsh in entry-common.S. In order to add support for
CONFIG_HAVE_ARCH_SECCOMP_FILTER without mangling the assembly too
badly, seccomp was moved into the syscall_trace() handler.

Additionally, the return value for secure_computing() is now checked
and a -1 value will result in the system call being skipped.
