Remove Git pre-commit hook

Since generated files are no longer stored in the repository, they
don't need to be up-to-date before committing.

-# Purpose
-#
-# This script does quick sanity checks before commiting:
-#   - check that generated files are up-to-date.
-#
-# It is meant to be called as a git pre-commit hook, see README.md.
-#
-# From the git sample pre-commit hook:
-#   Called by "git commit" with no arguments.  The hook should
-#   exit with non-zero status after issuing an appropriate message if
-#   it wants to stop the commit.
