[Buildroot] [PATCH 1/1] autobuild-run: show options along with their defaults

[André Erdmann]

Currently, the default values for options are printed at the end of the help
message, so there is a visual distance between the "--<option>" help and its
default value that increases with every newly introduced option.

Move them closer together by means of str-dict formatting, "%(key)s".

"[default: ]" cannot be used as it gets parsed by docopt,
using "Defaults to ...", "Not set by default", ... phrases instead.
