kconfig: Make localmodconfig handle environment variables

Browse source 
The commit 838a2e55e6
 kbuild: migrate all arch to the kconfig mainmenu upgrade

Broke make localmodconfig. The reason was that it added a
environment variable to the kconfig source, which the
streamline_config.pl could not handle.

This patch changes streamline_config.pl to handle kconfig sources
using environment variables in their names.
