firstboot: Include <crypt.h> for declaration of crypt() if needed (#7944)

Not every target system may provide a crypt() function in its stdlibc
and may use an external or replacement library, like libxcrypt, for
providing such functions.

See https://fedoraproject.org/wiki/Changes/Replace_glibc_libcrypt_with_libxcrypt.
