x86, um: sanitize uml sigcontext.h uses

Browse Source 
a) the only difference between sigcontext and sysdep/sigcontext
is that the former contains externs for two long-dead functions.
Removed, switched the only user to sysdep/sigcontext

b) asm/sigcontext.h is removable - that of underlying architecture
would get used.
