Remove stray -lmd from LDADD assignment

i386 FreeBSD 10.2-BETA2 r285662

Testing base system ntpd with old keys in /etc/ntp. Saw syslog entries every
couple of minutes like the following but the server seemed to operate OK
otherwise - as a client of unauthenticating servers.

Jul 21 16:16:53 rwsrv04 ntpd[2169]: crypto_encrypt:
error:00000000:lib(0):func(0):reason(0)

Generated new host keys with ntp-keygen. Now ntpd failed to start.

Jul 21 16:55:42 rwsrv04 ntpd[91910]: crypto_key: error:06074078:digital
envelope routines:EVP_PBE_CipherInit:keygen failure

An independent build of ntp 4.2.8p3 on 10.2-BETA2 worked fine.

ldd(1) revealed that the base system ntpd was linked to libmd but the working
ntpd was not. Also the base system ntp-keygen was not linked to libmd. All were
linked to libcrypto.

Checked the usr.sbin/ntp/ntpd/Makefile and saw what appeared to be a stray -lmd
in the LDADD= assignment at Line 31. Conditional code follows at Line 42 to
inclide libmd ONLY if OpenSSL has been disabled.

I removed the -lmd from Line 31 and rebuilt ntpd. All is good :-)
