[PATCH v2 2/3] builtin/grep: rename use_index to no_index

[Thomas Gummerer <t.gummerer@gmail.com>]

Switch the OPT_NEGBIT argument to a OPT_BIT argument, and rename the
corresponding use_index variable to a no_index variable.  This will make
the following step easier to follow.  No functional changes intended.
