[5/5] t/unit-tests: remove lib-oid.{c,h,o}

Commit Message

Seyi Kuforiji Feb. 20, 2025, 8:29 a.m. UTC

The `lib-oid.c`, `lib-oid.h`, and `lib-oid.o files` are no longer needed
since their equivalent functions have been implemented in unit-test.c
and unit-test.h. This removes redundant code and ensures all unit
test-related functionality is consolidated in a single location.

Drop references to lib-oid from our `Makefile`, and `meson.build` files
to prevent build errors due to missing files.
