Add globbing for mounting multiple GSP firmware files

Newer drivers have split the GSP firmware into multiple files so a simple match against gsp.bin in the firmware directory is no longer possible. This patch adds globbing capabilitis to match any GSP firmware files of the form gsp*.bin and mount them all into the container.
