bug#73214: swaylock-1.8.0 build failure

[Rutherther]

Hello,

better solution is to use pam, and we resolved how
in the #guix IRC channel. But for completion, to fix
swaylock/no-pam, libxcrypt has to be added, see:

---
(use-modules
 (guix packages)
 (gnu packages crypto)
 (gnu packages wm))

(define-public swaylock/no-pam
        (package
                (inherit swaylock)
                (name "swaylock-no-pam")
                (inputs
     (modify-inputs (package-inputs swaylock)
       (delete "linux-pam")
       (append libxcrypt)))))

swaylock/no-pam
