Generating the Recipe Map for the first time is very slow

[n8felton]

This appears to mostly be related to the get_git_commit_hash() function. As of right now, this hash is not actively being added to, or used by, the recipe map, so I'm proposing that it be bypassed during the recipe map generation.

Small comparison

With get_git_commit_hash() function

com.github.autopkg.n8felton-recipes
Function map_key_to_paths('identifiers', 'com.github.autopkg.n8felton-recipes') Took 6.1634 seconds
Function map_key_to_paths('shortnames', 'com.github.autopkg.n8felton-recipes') Took 5.9794 seconds
com.github.autopkg.recipes
Function map_key_to_paths('identifiers', 'com.github.autopkg.recipes') Took 8.5584 seconds
Function map_key_to_paths('shortnames', 'com.github.autopkg.recipes') Took 8.7585 seconds
com.github.autopkg.dataJAR-recipes
Function map_key_to_paths('identifiers', 'com.github.autopkg.dataJAR-recipes') Took 79.9220 seconds
Function map_key_to_paths('shortnames', 'com.github.autopkg.dataJAR-recipes') Took 81.3130 seconds

Without get_git_commit_hash() function
