cmDepends: Remove attempt to change directory that always fails

Nothing ever set `CompileDirectory` except `SetDirectory()`, but
nothing ever called that function. Therefore, `CompileDirectory`
was always empty for the attempt to change directory in `Check()`,
which therefore would always fail. Nothing was checking the result
and the code was always going to have no effect.
