[Qemu-trivial] [PATCH] optionroms: Silence intermediate file removal

[Jan Kiszka <jan.kiszka@siemens.com>]

The build process of optionroms spits out an "rm ..." line. Moreover, it
removes all .o files that can be handy for debugging purposes.

Disable automatic intermediate removal and only clean up the unneeded
and large .img and .raw files.
