mips: fix sigaction reporting
MIPS userland uses the same sigaction structure with a full signal
mask for old_sigaction and new_sigaction and does does not have
an sa_restorer field.
These changes have been tested on MIPS O32 big/little endian, MIPS N64
big endian and x86-64.
* signal.c (old_sigaction) [MIPS]: Add definition for MIPS.
(decode_old_sigaction) [MIPS]: Print sa_mask according to its definition.
(new_sigaction) [MIPS]: Add definition for MIPS.
