Add --firmwarepath to configure

Browse source 
Add a firmware path config option to configure.  Multiple directories
are accepted, with the usual colon as separator.  Default value is
${prefix}/share/qemu-firmware.  The path is searched in addition to the
current search path (typically ${prefix}/share/qemu).

This prepares qemu for the planned split of the prebuilt firmware blobs
into a separate project.

Distributions can also use this to get rid of the firmware symlink farm
and add -- for example -- /usr/share/seabios to the firmware path
instead.
