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. Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Cc: "Yann E.

- Use MD5 to encode passwords.

- The default. Wildly available, and pretty good.
- Although pretty strong, MD5 is now an old hash function, and
- suffers from some weaknesses, which makes it susceptible to
- brute-force attacks.
