Subject: [PATCH] backblaze2-b2: support alternative executable name

according to official doc backblaze.com/docs/cloud-storage-command-line-tools mentions the executable
is supposed to be called `b2`. Several distributions including nixpkgs renamed it to `backblaze-b2`
but it is annoying if you dont use boost's b2.
This commit makes it possible to override the executable name to
something else.
