We don't check str_dup() return value and never free it.  While both
things are irrelevant in practice, let's just clean it up by working on
argv[0] directly and avoiding the str_dup().

Nobody after us needs these parts of the argv[0] string anyway.

This patch is inspired by previous work from Anshuman Tewari [1].
