btrfs-progs: hash-speedtest: benchmark the configured backend 

Change what hash-speedtest benchmarks according to the
--with-crypto=backend option. Until now it would run the same version
under different names inherited from the builting.

At configure time detect availability of all backends and define all
macros.
