[PATCH v2 6/7] worktree: rename copy-pasted variable

["Martin Ågren" <martin.agren@gmail.com>]

As the commit message of 04a3dfb8b5 ("worktree.c: check whether branch
is bisected in another worktree", 2016-04-22) indicates, the function
`is_worktree_being_bisected()` is based on the older function
`is_worktree_being_rebased()`. This heritage can also be seen in the
name of the variable where we store our return value: It was never
adapted while copy-editing and remains as `found_rebase`.

Rename the variable to make clear that we're looking for a bisect(ion),
nothing else.
