Exclude `*/.extensions` from grep/reencrypt

The `.extensions` directory can contain extensions code, for example as
git submodules, that have `.gpg` files as part of their code but that
are not files encrypted with the PGP keys of our password store.

One example is `pass-tomb`, that contains `.gpg` files in `tests/gnupg`,
but there are more, like `pass-update`, `pass-otp`, etc.

However those `.gpg` files in the `.extensions` directory are currently
processed by the `grep` and `reencrypt` functions of `pass`.

At best this can cause errors to be shown to the user when
grepping/reencrypting, and at worst it can cause files in the
`.extensions` directory to be decrypted and returned as part of a
search, or reencrypted with the incorrect PGP keys.

This patch tries to mitigate that issue by removing the `*/.extensions`
directories from the list of processed `.gpg` files for the
grep/reencrypt functions.

However this patch is not perfect as it does not take into account the
fact that the `.extensions` directory can be renamed to something else
using `PASSWORD_STORE_EXTENSIONS_DIR`. But knowing if this
`PASSWORD_STORE_EXTENSIONS_DIR` is inside the `PREFIX` or not and
formatting the path exclusion for `find` accordingly could require a
fair bit of additional logic that I am not sure how you want to
implement.
