libaio: bump to 0.3.111

Until now, libaio contained some architecture specific code to do the
syscalls. In fact, it contained a generic variant of the code called
syscall-generic.h, but it was showing a warning when it was used, as
if it was "not safe". Consequently, in Buildroot, we had chosen to
support libaio only on a the subset of architectures that were
explicitly handled by libaio.

However, between 0.3.110 and 0.3.111, libaio upstream entirely dropped
the architecture-specific code:

  https://pagure.io/libaio/c/97fd3fc0195500e616e34047cba4846164c411d9?branch=master

Consequently, in this patch, we:

 - Bump libaio to 0.3.111.

 - Switch to the new upstream at https://pagure.io/libaio/.

 - Drop the 0001-arches.patch patch, which was adding support for
   MIPS, since we no longer need architecture-specific code.

 - Update the remaining patches, and Git-format one of them which
   wasn't Git-formatted.

 - Drop the BR2_PACKAGE_LIBAIO_ARCH_SUPPORTS option and all its uses.
