mips: signal: move sigcontext declarations to header

Browse Source 
Function declarations should be in a shared header to ensure the
prototypes match the definition:

arch/mips/kernel/signal.c:439:5: error: no previous prototype for 'setup_sigcontext' [-Werror=missing-prototypes]
arch/mips/kernel/signal.c:516:5: error: no previous prototype for 'restore_sigcontext' [-Werror=missing-prototypes]
