[MIPS] Fix symbols being filtered out from target side of diff if target object contains .NON_MATCHING markers (#250)

* Fix filtering out symbols from the target side that have a symbol with the same name and a `.NON_MATCHING` suffix.

- Target side: Show all the symbols except the `.NON_MATCHING` ones.
- Base side: Ignore all the `.NON_MATCHING` symbols and also ignore the ones with the same name without the suffix
