libcap2: fix build with and without libpam

* Add libpam to depends if DISTRO_FEATURES contains pam.

* Fixes the following compile error, when libpam-dev is installed
  on the host, but not built for the target:

pam_cap.c:19:34: error: security/pam_modules.h: No such file or directory
pam_cap.c:20:34: error: security/_pam_macros.h: No such file or directory
