This fixes the unexpected growth of stack in child process, which
is caused by stack checking code in runtime.sigfillset called from
runtime.sigset while clearing the signal handlers in child process.
The redundant stack checking code is generated due to missing
'//go:nosplit' directive that should be annotated for
runtime.sigfillset.

They do not match the file name patterns of
*_GOOS
*_GOARCH
*_GOOS_GOARCH
therefore the implicit linux constraint was not being added.

Follow CL 93655 which removed the (commented-out) usage of this
function.
Also remove unused constant _RLIMIT_AS and type rlimit.

On 64-bit big-endian GNU/Linux machines we need to treat sigset as a
single uint64, not as a pair of uint32 values. This fix was already made
for s390x, but not for ppc64 (which is big-endian--the little endian
version is known as ppc64le). So copy os_linux_390.x to
os_linux_be64.go, and use build constraints as needed.
