sys-firmware/edk2-ovmf: workaround: do not install broken qemu config

As a temporary workaround do not install

  /usr/share/qemu/firmware/40-edk2-ovmf-x64-sb-enrolled.json

We are currently not shipping the necessary OVMF_VARS.secboot.fd file

+DOC_CONTENTS="This package contains the tianocore edk2 UEFI firmware for 64-bit x86
+virtual machines. The firmware is located under
+	/usr/share/edk2-ovmf/OVMF_CODE.fd
+	/usr/share/edk2-ovmf/OVMF_VARS.fd
+	/usr/share/edk2-ovmf/OVMF_CODE.secboot.fd
+
+If USE=binary is enabled, we also install an OVMF variables file (coming from
+fedora) that contains secureboot default keys
+
+	/usr/share/edk2-ovmf/OVMF_VARS.secboot.fd
+
+If you have compiled this package by hand, you need to either populate all
+necessary EFI variables by hand by booting
+	/usr/share/edk2-ovmf/UefiShell.(iso|img)
+or creating OVMF_VARS.secboot.fd by hand:
+	https://github.com/puiterwijk/qemu-ovmf-secureboot
+
+The firmware does not support csm (due to no free csm implementation
+available). If you need a firmware with csm support you have to download
+one for yourself. Firmware blobs are commonly labeled
+	OVMF{,_CODE,_VARS}-with-csm.fd
+
+In order to use the firmware you can run qemu the following way
+
+	$ qemu-system-x86_64 \
+		-drive file=/usr/share/edk2-ovmf/OVMF.fd,if=pflash,format=raw,unit=0,readonly=on \
