package/iwd: fix S40iwd check-package warnings

Fix fix S40iwd check-package warnings:

- package/iwd/S40iwd:3: Do not include path in DAEMON
  (https://nightly.buildroot.org/#adding-packages-start-script)

- package/iwd/S40iwd:4: Incorrect PIDFILE value
  (https://nightly.buildroot.org/#adding-packages-start-script)

Since this commit fixes lib_sysv.Variables check-package warnings
in S40iwd, this commit also removes the .checkpackageignore entry.
