20_linux_tboot: efi logic was inverted

There was a RAID0 system that could boot normally, but not through
a tboot launch. The problem was that the logic in this script
incorrectly appended 'noefi' to the grub.cfg module2 kernel stanza.

When 'noefi' was removed from that stanza, the system could boot
through a tboot launch. This patch corrects the logic in the script.
