Corrections in metastore's git hooks

Two corrections were made in the Git hooks of Metastore.

 1) The shebang at the start of the scripts now uses the absolute adress of
    our installed bash, not the relative `.local/bin/bash'. Note that it is
    possible to use Git within subdirectories and in that scenario, the
    `.local' will fail.

 2) The `$$user' section was removed from the command to find the user's
    group. With the user as an argument, `groups' may print the user's name
    first, then their list of groups. When this happens, the script would
    be just repeating the user's name. But the raw `groups' command will
    list the groups of the running user.
