seabios 1.13 will be released later this month.  This patch updates the
seabios submodule and binaries in qemu to a snapshot of git master.
That will increase the test coverage of the upcoming seabios release and
will also make the number of changes smaller when we update to the final
1.13 release during qemu code freeze for 4.2.

v3: add ahci bugfix
v2: build binaries with gcc 4.8.5 instead of gcc 8.3.1 (rhel7).
