Git.pm: make hash size independent

The cat_blob function was matching on exactly 40 hex characters. This won't work with SHA-256, which uses 64-character hex object IDs. While it should be fine to simply match any number of hex characters since the output is space delimited, be extra safe by matching either exactly 40 or exactly 64 hex characters.
