Fixed core pattern to use correct dlt-cdh install path

- 50-coredump.conf is now generated and installed
  by cmake and uses @CMAKE_INSTALL_PREFIX@ for setting
  path to dlt-cdh
- README updated

 Temporary replacement of default crash handler:
 If you don't want to make the change persistent just become root (not sudo) and execute the following ("man core" for details):
-echo "|/usr/local/bin/dlt-cdh %t %p %s %e" > /proc/sys/kernel/core_pattern
+echo "|/usr/local/bin/dlt-cdh %t %p %s %e" > /proc/sys/kernel/core_pattern (replace /usr/local/bin with the path dlt-cdh has
+been installed to)

-We have to install "50-coredump.conf" to "/usr/lib/sysctl.d/" which is done automatically by "make install".
-Unfortunately we also have to remove abrt with "yum remove abrtd*" because this ruthlessly overwrites our change at

 To enable the core dump handler without rebooting we have to execute "sysctl -p /usr/lib/sysctl.d/50-coredump.conf"
