[anaconda:rhel7/master] Add option help text for --image and --dirinstall flags (#1056791)

Resolves: rhbz#1056791
The help text is not added in-line, because if more complete help text
were added in-line, the source in anaconda would get very hard to read.
Also, the help text is a lot easier to format out-of-line.
