scripts: Support custom Git URLs in build-many-glibcs.py

Browse Source 
Use environment variables to provide mirror URLs to checkout
sources from Git. Each component has a corresponding env var
that will be used if it's present: <component>_GIT_MIRROR.

Note that '<component>' should be upper case, e.g. GLIBC.

It is also possible to use different Git URL for cloning sources
