builtin/grep: add grep.fallbackToNoIndex config
Currently when git grep is used outside of a git repository without the
--no-index option git simply dies. For convenience, add a
grep.fallbackToNoIndex configuration variable. If set to true, git grep
behaves like git grep --no-index if it is run outside of a git
repository. It defaults to false, preserving the current behavior.
