Autotools: Remove obsolete crypt link override due to OpenSSL (#14863)

Browse Source 
OpenSSL versions before 0.9.7 provided its own crypt() function (and
des_* functions) in its Crypto library that interfered with the
implementation relying on crypt() from some other crypt library. This is
at this point obsolete as crypt and other functions that caused clashes
were removed in OpenSSL version 1.1.0.

In OpenSSL 0.9.7 des_old.c and des_old.h files were provided for BC.

In OpenSSL 0.9.8 crypt() function was renamed to _ossl_old_crypt and the
crypt macro definition was commented out in the des_old.h header.

In OpenSSL 1.1.0 the old DES API was removed, meaning OpenSSL's crypto
library no longer provides crypt() function as it used to.
