gnuplot: add x11 PACKAGECONFIG

Currently, gnuplot recipe requires the x11 distro feature to be built.
However, X11 is not needed for running gnuplot as long as we don't use
a gnuplot X11 terminal.
This commit adds the x11 package config used to make the need of x11
distro feature optional to build gnuplot. `features_check` inherit is removed as
any of the functionalities of this class is now used.
