These libraries don't install anything, so they shouldn't have a
PACKAGE setting.  This avoids surprising behaviour in future if
e.g. manpages are added to an internal library.

MIT KRB5 does not support telnet. This is because telnet uses 3DES
encryption, which requires 3DES encrypted keys in the KDC database.
As MIT had deprecated and removed 3DES support about a decade ago,
telnet is not supported.

OPENSSL_API_COMPAT can be used to specify the OpenSSL API version in
use for the purpose of hiding deprecated interfaces and enabling
the appropriate deprecation notices.

This change is a NFC while we're still using OpenSSL 1.1.1 but will
avoid deprecation warnings upon the switch to OpenSSL 3.0.

A future change should migrate to use the OpenSSL 3.0 APIs, or just
remove libtelnet.
