binfmt_misc: fix binfmt_misc priority

Browse Source 
commit ee3aebdd8f upstream.

Commit 74641f584d ("alpha: binfmt_aout fix") (May 2009) introduced a
regression - binfmt_misc is now consulted after binfmt_elf, which will
unfortunately break ia32el.  ia32 ELF binaries on ia64 used to be matched
using binfmt_misc and executed using wrapper.  As 32bit binaries are now
matched by binfmt_elf before bindmt_misc kicks in, the wrapper is ignored.

The fix increases precedence of binfmt_misc to the original state.
