package.bbclass: add SHLIBSSEARCHDIRS to define where to search for shlib providers

* when package contains some files matching "^.*\.so", but in directory
  not default linker search paths (e.g. /opt/package/bundled-lib/libfoo.so)
  don't register it as libfoo provider, because it's possible that there
  is different package providing libfoo.so in ${libdir} and that would
  be better shlib provider for other packages to depend on
* recipes providing libs intentionally in some other directory can
  define own SHLIBSSEARCHDIRS value

WIP: Add KERNEL_EXTRA_ARGS?
gtk+: Add PACKAGECONFIG for directfb

* building without x11 doesn't work, because it sets default
  gdkbackend to x11 and then requires cairo-xlib to be available
* checking for CAIRO_BACKEND... no
  configure: error: Package requirements (cairo-xlib >= 1.6) were not met:

  No package 'cairo-xlib' found
