system cfg: remove mkpasswd MD5 format option
As SHA256 is now default, removing weak MD5 option. C libraries now
all support the SHA methods.
glibc 2.7+
uclibc (bdd8362a88 package/uclibc: defconfig: enable sha-256...)
musl 1.1.14+
One issue this would prevent, is a host tool issue with a FIPS enabled
system where weak ciphers/methods are disabled. It seems the crypt(3)
call is impacted by /proc/sys/crypto/fips_enabled (per crypt(3) man
page). It results in mkpasswd returning "(EPERM) crypt failed."
Rather then create a Buildroot host dependency check, this patch
removes the potential corner case from being selected.
