Bugfix and small improvements release

This relase adds few minor features:

• a vfat partition is added to export data more easily from the machine under test
• debootstrap now uses the minbase variant to lower disk usage
• some tools (cpuid, msr-tools and dmidecode) are explicitely added to the installed ones
• grub entries have been added for the EFI shell and Keytool utility; those entries might be more practical than the EFI ones (which might be removed in a future release)

The chipsec.ko is now explicitely built when installing Chipsec, following upstream changes.
