deps.c: remove filtered_depend functions
filtered_dep was duplicating an alpm_depend_t solely for the purpose of overriding its depmod and would effectively cause alpm_checkdeps to ignore ALPM_TRANS_FLAG_NODEPVERSION if the duplication failed. Manually overriding/restoring the depmod for the original depend removes the duplication as a point of failure and fixes a memory leak where the duplicated depend was not being properly freed.
