systemd-boot: disable RMC for systemd-boot EFI_PROVIDER

Previously the RMC library was always linked into systemd-boot. Non
rmc-boot EFI_PROVIDERs will not build the rmc.db and userspace tool and
therefore linking the library into these bootloaders is redundant.
This change disables RMC completely when the EFI_PROVIDER is not rmc-boot.

The default EFI_PROVIDER in meta-intel is rmc-boot. To use systemd-boot
without RMC, set EFI_PROVIDER to systemd-boot in your conf/local.conf.

Example:

EFI_PROVIDER = "systemd-boot"
