bitbake: bitbake-setup: add 'metavar' for self-descriptive parameters

Add a metavar to the argparse options to have a self-descriptive help text.
Otherwise argpase defaults to use the argument name in all-uppercase.

Before:

usage: bitbake-setup [-h] [-d] [-q] [--color COLOR] [--no-network] [--global-settings GLOBAL_SETTINGS] [--setting SETTING SETTING SETTING]
                     {list,init,status,update,install-buildtools,settings} ...

After:

usage: bitbake-setup [-h] [-d] [-q] [--color COLOR] [--no-network] [--global-settings PATH] [--setting SECTION SETTING VALUE]
                     {list,init,status,update,install-buildtools,settings} ...
