New issue by phrdina on void-packages repository

https://github.com/void-linux/void-packages/issues/23495

Description:
### System

* xuname:  
  Void 5.7.7_1 x86_64 x86_64 AuthenticAMD uptodate rF
* package:  
  qemu-5.0.0_2

### Expected behavior
edk2 json firmware files installed by qemu package should be in `/usr/share/qemu/firmware/` directory.

### Actual behavior
They are currently installed in `/usr/lib/qemu/firmware/` directory which is incorrect. If you check QEMU documentation for the firmware json files [https://git.qemu.org/?p=qemu.git;a=blob;f=docs/interop/firmware.json;hb=HEAD](url) it has an explicit list of directories where the firmware json files should be and libvirt looks for this files only at these directories in order to provide the installed firmwares to users or to management applications like virt-manager.

### Steps to reproduce the behavior
`xbps-install qemu`
`xbps-query -f qemu`
