Summary:
The use of `tee /dev/stderr` failed when running as a child process
under Node for some reason. (I haven’t been able to figure out why—it
works fine when run as a standalone script or when run as a child
process under Python.) This is also technically Linux-specific, so I’ve
changed it to use a process substitution. After looking around for a
bit, there doesn’t seem to be a way to do this in a way that is
portable, uses only POSIX shell features, and doesn’t create temporary
files all at the same time, so the script is now run under `bash`.
Test Plan:
Run `yarn travis` and note that the `ensure-flow.sh` output no longer
contains the line `tee: /dev/stderr: No such device or address`.

Summary:
This fixes two problems in the previous version:
- A new JS file not checked into git, but with a `@flow` directive,
would cause `ensure-flow` to fail, because one list of files was
from `git grep` and the other was from `find`.
- Only the hard-coded directories `src config scripts` were searched.
Now, we search all JS files checked into Git, except for some hard-coded
exceptions, namely `flow-typed`.
Test Plan:
1. Add `foo.js`, not checked into Git. Note that `ensure-flow` passes.
2. Add `@flow` to `foo.js`, and note that `ensure-flow` still passes.
3. Remove `@flow` from `.eslintrc.js`, and note that `ensure-flow`
fails and nicely prints the filename. (Note: this file is at the
repository root.)
4. Create a file `echo stuff >$'naughty\nfilename.js'`, and note that
`ensure-flow` has the correct behavior in both positive and
negative cases.
wchargin-branch: ensure-flow-improvements
This script ensures that either //@flow or //@no-flow is present in
every js file. Every existing js file that would fail this check has
been given //@no-flow, we should work to remove all of these in the
future.
Test plan:
I verified that `yarn travis` fails before fixing the other js files,
and passes afterwards.
