Pin bcrypt until passlib is fixed/removed

Currently there is an incompatibility with the latest version of passlib
and the version of bcrypt we have specificed in the upper-constraints
[1]. Passlib also apears to be unmaintained [2] at this point and we're
investigating the removal of the library from Keystone. For the time
being this pins bcrypt to a version that is known to work with the
latest passlib that is available.
