compiler-rt/lib: Add .Linterceptor_sigsetjmp

Older GNU assemblers generate R_X86_64_PC32 relocation against
defined non-weak global branch targets with default visibility.  A
linker may issue an error when building a shared library.  Add a local
alias, .Linterceptor_sigsetjmp, to __interceptor_sigsetjmp to avoid
R_X86_64_PC32 relocation for "jmp __interceptor_sigsetjmp" with older
GNU assemblers.
