Arch Linux

Description:
The json config files for the shipped edk2 firmware are packaged in usr/share/qemu/firmware/ in the qemu / qemu-headless package.
The edk2 firmware is packaged in usr/share/qemu/ qemu-arch-extra an optional dependency of qemu / qemu-headless.
Since libvirt 5.8 the presence of json files in /usr/share/qemu/ or /etc/qemu/firmware causes firmware specified in /etc/libvirt/qemu.conf to be ignored.
This causes libvirt to disable EFI mode due to missing firmware.

Placing the edk2 firmware into same package as its json configs or removing all of the edk2 files would prevent such firmware detection failure.
If the edk2 files were removed or split from qemu / qemu-headless it would also allow firmware to specified in /etc/libvirt/qemu.conf
as a workaround until json files are added to ovmf.

Additional info:
* qemu 4.1.1-1
*  FS#64175 
*  FS#64206 

Steps to reproduce:
Install libvirt then start libvirt observe edk2 firmware is not located.
