[Buildroot] [PATCH] package/e2fsprogs: backport build fix for rhel5 due to missing magic

[Max Filippov <jcmvbkbc@gmail.com>]

RHEL 5.x does have magic.h, but it does not define all expected symbols. In
particular, the NO_CHECK symbols were only added in file 4.20 and RHEL 5.x
is using 4.17.

Add substitute defines to allow continued usage of magic but without the
requested exclude checks.
