Ingo Franzki 2f87cba1c7 util_opt: Change util_opt_init() to honor current command, if set ...

Function util_opt_init() build the option string for getopt_long().
If a command has been set via util_opt_set_command(), then util_opt_init()
must honor that command and only add those options that match the command,
or are command independent.

That way the same option can be used in different commands with different
flags and different argument settings. E.g. for command 'a' option '-x'
might require an argument, for command 'b' the same option '-x' might not
require an argument.

The behavior of util_opt_init() is unchanged if no command is set, and
also if different commands use the same option, but with the same flags
and argument settings. Currently only the zkey tools set a command, but
use unique options per command.
