main: Don’t print translation header with `--help`
The correct way to tell g_option_context_new()
not to print any
information after the options is to pass NULL
. Passing the empty
string results in a call to gettext ("")
, which returns the
translation’s header.
This fixes the output of accounts-daemon --help
.
