host,test: Remove unneeded vb1 rsa functions

Browse Source 
Another in a continued stream of refactoring.  This change removes more
of the vb1 rsa library code and associated tests, in favor of their vb2
equivalents.  This change touches only host-side code and its tests, not
firmware.

BUG=chromium:611535
BRANCH=none
TEST=make runtests; emerge-kevin coreboot depthcharge
