wxwidgets: fix install errors

There are errors during do install. So link files 'wx-config' and 'wxrc'
are not created, and rename failed either:

| CMake Error: failed to create symbolic link '/usr/bin/wx-config': Permission denied
| Error renaming from "/usr/bin/wxrc" to "/usr/bin/wxrc-3.1": No such file or directory
| CMake Error: failed to create symbolic link '/usr/bin/wxrc': Permission denied

Respect variable 'DESTDIR' to make it work as expect.

And package ${libdir}/wx/config/gtk3-unicode-3.1 to ${PN}-dev that
/usr/bin/wx-config from ${PN}-dev links to it.
