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.
