The __getrandom_nocancel function returns errors as negative values
instead of errno. This is inconsistent with other _nocancel functions
and it breaks "TEMP_FAILURE_RETRY (__getrandom_nocancel (p, n, 0))" in
__arc4random_buf. Use INLINE_SYSCALL_CALL instead of
INTERNAL_SYSCALL_CALL to fix this issue.
But __getrandom_nocancel has been avoiding from touching errno for a
reason, see BZ 29624. So add a __getrandom_nocancel_nostatus function
and use it in tcache_key_initialize.
