[Buildroot] [PATCH 1/2] system cfg: default mkpasswd to SHA

[Matt Weber]

This patch drops the comment about checking the C libraries version as
they now all support it by default
    glibc 2.7+
    uclibc (bdd8362a88 package/uclibc: defconfig: enable sha-256...)
    musl 1.1.14+

This patch updates the help text and changes the default mkpasswd
method to SHA256 from MD5
