rmc: add support for alternative EFI bootloaders
PATCH 1/1 rmc: add support for alternative EFI bootloaders
RMC was previously configured to work only with the systemd-boot EFI bootloader. With this commit we can specify alternative bootloaders by setting the RMC_BOOTLOADER variable in local.conf. If RMC_BOOTLOADER is not set systemd-boot will be used by default.
Example for grub-efi:
RMC_BOOTLOADER = "grub-efi"
