`memray run` overwrites `sys.argv[0]` even when `-I` or `-P` is used

[Matt Wozniski]

memray run tries to match the updates to sys.path that are performed by the interpreter itself when it starts. When those path updates are suppressed (by the -I or -P command line flags or their corresponding environment variables), Memray's emulation winds up overwriting paths in sys.path that needed to be left alone.
