[PATCH v7 2/7] wrap-for-bin: Make bin-wrappers chainable

[benoit.person@ensimag.fr]

From: Benoit Person <benoit.person@ensimag.fr>

For now, bin-wrappers (based on wrap-for-bin.sh) redefine some
environnement variables (like $GITPERLLIB). If we want to chain to
those scripts and define one of those variables before, our changes
will be overwritten.

This patch simply makes the bin-wrappers prepend their modifications
rather than redefine the vars.
