completion: add space after config variable names also in Bash 3

Browse Source 
In be6444d1ca (completion: bash: add correct suffix in variables,
2021-08-16), __git_complete_config_variable_name was changed to use
"${sfx- }" instead of "$sfx" as the fourth argument of _gitcomp_nl and
_gitcomp_nl_append, such that this argument evaluates to a space if sfx
is unset. This was to ensure that e.g.

	git config branch.autoSetupMe[TAB]

correctly completes to 'branch.autoSetupMerge ' with the trailing space.
This commits notes that the fix only works in Bash 4 because in Bash 3
the 'local sfx' construct at the beginning of
__git_complete_config_variable_name creates an empty string.

Make the fix also work for Bash 3 by using the "unset or null' parameter
expansion syntax ("${sfx:- }"), such that the parameter is also expanded
to a space if it is set but null, as is the behaviour of 'local sfx' in
Bash 3.
