libpam-tacplus: new package

[Thomas:
  - change the inclusion location in package/Config.in to be with the
    other linux-pam plugins.
  - fix indentation of the Config.in file.
  - fix build of the package when a toolchain without SSP support is
    used.
  - fix installation location of the PAM module: it was installed in
    /usr/lib/security, while all other PAM modules are in
    /lib/security.
  - adjust the ordering of the variables in the .mk file to be a bit
    more logical.
  - remove passing of $(TARGET_CONFIGURE_OPTS) in <pkg>_CONF_ENV as it
    is not needed: it is already done by the autotools-package
    infrastructure.]
