polkit: Switch PAM files to common-*

Add a new OS option to polkit meson: "openembedded" and use this to
set PAM include to common-* which matches OE-Core libpam.

This also may fix a non-reproducibility since polkit meson system tried
to detect the host (compiling) OS and changed PAM config from the
detected value.

+Subject: [PATCH] meson.build: Support "openembedded" OS for PAM config
+
+In Openembedded, same as Suse/Solaris: PAM files are common-*:
+* PAM_FILE_INCLUDE_AUTH: common-auth
+* PAM_FILE_INCLUDE_ACCOUNT: common-account
+* PAM_FILE_INCLUDE_PASSWORD: common-password
+* PAM_FILE_INCLUDE_SESSION: common-session
+See OE-Core libpam recipe.
+
+NB: This is also the same config as Debian but its not mentioned in the
+code.
