RISC-V: tighten post-relocation-operator separator expectation
As per the spec merely a blank isn't okay as a separator, the operand to the relocation function ought to be parenthesized. Enforcing this then also eliminates an inconsistency in that lui t0, %hi sym lui t0, %hi 0x1000 were accepted, but lui t0, %hi +sym lui t0, %hi -0x1000 were not.
