cmd/internal/objfile: make lookupFunc an alias type

In the x/arch repo, CL 45098 introduced SymLookup type, replacing
the unnamed function type for lookup functions. This affects the
signature of x86asm.GoSyntax. In particular, it cannot convert
one named type, namely lookupFunc, to the other without an
explicit cast. Make lookupFunc unnamed to fix.
