[release,docs] Install the example grid files into docdir and not includedir.

Before this patch all the example files describing grids were installed below
the include path. With this patch they are installed in the documentation of
the package which seems more suitable.

[release,cmake] Only build programs below src with --enable-extra-utils

With automake everything below the src subdir is only processed if
configured with --enable-extra-utils. With this patch the same behaviour
applies when using cmake with that option in th CONFIGURE_FLAGS or by
providing -DENABLE_GRID_EXTRA_UTILS:Bool=True to cmake.

[cmake,release] Fixes building programs in src/gridinfo-gmsh.

Some wrong variables (ALBERTA_[23]D_FOUND instead of
ALBERTA_[23]D_LIB_FOUND) were used here which resulted in
missing programs. In addition directives for one were missing.
This is fixed by this patch together with some copy and paste error
and reducing to one install directive.
