libsrp6a-sha512: disable BN_mod_exp_mont_word() with LibreSSL
When building libimobiledevice with LibreSSL 3.9 it fails with an
implicit declaration for BN_mod_exp_mont_word().
This function was removed from the public symbols in LibreSSL because it
is rarely used where "BN_mod_exp() and BN_mod_exp_mont() will use the
word optimization when appropriate."
