Allow build systems without standard cc to successfully run the
dependency checking helper scripts from the Makefile.
This supports custom compilers specified by the common CC environment
variable, preprocessors given as CPP and additional preprocessor flags
from CPPFLAGS.
Additional flags from CFLAGS and LDFLAGS are considered for compiling/linking.
Overall, this facilitates cross-compilation and similar setups.

Finding systemd devel packages using libsystemd does not work as
in RHEL based distro the package name is systemd-devel and for
deb/ubunutu it is libsystemd. It is also giving false result when
podman rpm is built with systemd but hack/systemd_tag.sh does not
return anything.
Install systemd-devel package in build_rpm.sh script
Moving to systemd/sd-daemon.h header files which comes from devel
packages fixes the issue.

If the systemd development files are not present on the system which
builds podman, then `podman events` will error on runtime creation.
Beside this, a warning will be printed when compiling podman.
This commit mainly exists because projects which depend on libpod
would not need the podman event support and therefore do not need to
rely on the systemd headers.
