Revert "Make ex1.c and ex4.c be executable on any systems"

Using /usr/bin/env tcc doesn't work as it was reported.  Revert to
using the full path which fails if the user installs tcc in non-default
location.  Then again this is just an example.

This reverts commit 27a428cd0fae475d7377e1dbe218c064ee217d85.
