MIPS: Handle microMIPS jumps in the same way as MIPS32/MIPS64 jumps

is_jump_ins() checks for plain jump ("j") instructions since commit
e7438c4b893e ("MIPS: Fix sibling call handling in get_frame_info") but
that commit didn't make the same change to the microMIPS code, leaving
it inconsistent with the MIPS32/MIPS64 code. Handle the microMIPS
encoding of the jump instruction too such that it behaves consistently.
