bcrypt: fix C compatibility code

The bcrypt implementation must append a zero byte to the user provided key
to be compatible to C implementations.
This will change the user provided key if the slice has enough capacity to
hold the extra zero byte.

This change always allocates a new slice for the C-compatible key.

Fixes golang/go#20425
