support acpi firmware performance data (FPDT)

Prefer firmware-provided performance data over loader-exported ones; if
ACPI data is available, always use it, otherwise try to read the loader
data.

The firmware-provided variables start at the time the first EFI image
is executed and end when the operating system exits the boot services;
the (loader) time calculated in systemd-analyze increases.
