Timeout for decrypt

Sometimes, usually because of proprietary binaries related to keymaster,
decrypt will hang waiting for the keymaster to initialize forever. This patch
enables a timeout so that we don't get stuck trying to decrypt forever.
A timeout is especially important when dealing with the default password
because the user has no option to cancel when TWRP tries to decrypt.

NOTE: This patch only adds a timeout for FDE. FBE will require some special
handling because we need access to some static data and that data is not
available across a fork.

Special thanks to nkk71 for cleaning up some issues in my patch set.
