Tim Schumacher 5f99934dce Userland: Consolidate most PATH resolving into a single implementation
We previously had at least three different implementations for resolving
executables in the PATH, all of which had slightly different
characteristics.

Merge those into a single implementation to keep the behaviour
consistent, and maybe to make that implementation more configurable in
the future.
