RSA: Fix signature verification for shorter signatures

gpg can produce a signature file where length of signature is less than the
modulus size because the amount of space an MPI takes up is kept as low as
possible by discarding leading zeros.  This regularly happens for several
modules during the build.

Fix it by relaxing check in RSA verification code.

Thanks to Tomas Mraz and Miloslav Trmac for help.
