[PATCH 5/7] Add calls to git_extract_argv0_path() in programs that call git_config_*

[Steffen Prohaska <prohaska@zib.de>]

Programs that use git_config need to find the global
configuration.  When runtime prefix computation is enabled, this
requires that git_extract_argv0_path() is called early in the
program's main().

This commit adds the necessary calls in the programs that use
git_config.
