Fix broken build when using system zxcvbn (#10717)

* Fix broken build when using system zxcvbn

Fixup of zxcvbn include statement added in 5513ff5. A zxcvbn/ directory
prefix breaks building with system zxcvbn. Remove this prefix to align
this include statement with ones present in other files. Add zxcvbn
libraries as dependency to CliTest.

* Move src/zxcvbn/ to src/thirdparty/zxcvbn
