core: if the bootloader supports it, determine firmware and boot loader delay

This allows us to print simple performance data of all parts of the boot now:

- firmware
- boot loader
- kernel
- initrd
- userspace

This only works for bootloaders which support passing TSC data via EFI
variables. As of now that's only gummiboot.
