Fixed small padding error in the PKCS#1 PSS code.

The existing LTC code for padding meassages for PSS signatures
contained a small error. In particular, the PSS-passing algorithms is
supposed to be given (bitlength of key - 1) as an argument. The LTC
code passes (bitlength of key), and subtracts 1 in the middle of the
PSS-padding. This subtraction unfortunately comes too late: a
calculation using that argument has already been made. Fortunately,
this bug only appeared if the bit-length of the key was 1 mod 8, and
so is unlikely to show up in practice. Still, this patch fixes the
problem.
