security/tpm: improve tlcl_extend() signature

Browse Source 
Until now tcg-2.0/tss.c was just assuming certain buffer size and
hash algorithm. Change it to accept digest type, which the call sites
know.

Also drop `uint8_t *out_digest` parameter which was always `NULL`
and was handled only by tcg-1.2 code.
