acpi-fpdt: Use kernel fpdt parsing

On some kernels/distros (RHEL/aarch64) /dev/mem is
turned off. This means that the ACPI FPDT data is
missing from systemd-analyze output when /dev/mem
fails to provide the boot times.

Instead recent kernels can export that data from
/sys/firmware/acpi/fpdt/boot/ entries. Use that
information if available first.
