[bug#70158] [PATCH v2 2/3] gnu: scilab: Fixup and improve compilerDetection.sh script.

[Nicolas Graves via Guix-patches via <guix-patches@gnu.org>]

The content of this patch has been merged upstream and will be provided
in the next version of scilab.

As these improvements are not blocking, this patch can be discarded. 1
and 3 are still useful though.
