Makefile: detect corosync and libdlm via pkg-config

The Makefile currently checks for corosync and libdlm headers by probing
/usr/include directly. This breaks in cross-compilation environments
because the headers may be located in a sysroot rather than the host
filesystem.

Use pkg-config to detect the presence of corosync and libdlm instead.
