Hardcode a.out related constants

The OMAGIC, NMAGIC and ZMAGIC constants, related to the legacy a.out
binary format, are no longer available in the headers of all
architectures, due to this binary format being deprecated. For that
reason, util-linux fails to build.

We therefore take the approach used in newer versions of
util-linux-ng: hardcoding those values. See
http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git;a=commitdiff;h=e9eb4dad0ece03914f67f6d1ded74cfbbe694ba4
