detect/bytejump: don't reuse content flag

To avoid future problems with overlapping flag values, give bytejump
its own DETECT_BYTEJUMP_OFFSET_VAR flag.

The values are currently not overlapping, so this patch should have
no side effects.

(cherry picked from commit 101452056d559b4e5eab27c2d9fb651d2e32c412)
