MIPS32: Make sigset64_t equal to sigset_t
sigset_t is already large enough on mips so use the same principle
as on LP64 architectures: typedef sigset_t sigset64_t
Also prevent accessing sa_restorer field for architectures which
don't define SA_RESTORER in signal_test.
This allows compilation of signal_test.
Test: bionic-unit-tests in QEMU (MIPS32)
