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.
