kernel: don't copy .so.dbg files into kernel source install

In 3.16+ x86-64 kernel builds produce a vdso64.so.dbg file. If this file is
copied into the kernel source install multiple QA failures are triggered.
Specifically, this file triggers a debug package split that results in
files installed but not shipped, and invalid .debug file errors.

By ensuring that .so files are not copied, we avoid this incorrect split
with no impact on future build phases.

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

update-rc.d: Allow to use different initscripts provider

* until now all recipes were respecting VIRTUAL-RUNTIME_initscripts
  variable but commit bba835fed88c3bd5bb5bd58962034aef57c408d8
  hardcoded "initscripts" runtime dependency

SIGGEN_EXCLUDERECIPES_ABISAFE: add initscripts

* update-rc.d now adds initscripts dependency even to allarch recipes
  making them effectively TUNE_PKGARCH, "fix" it by excluding
  initscripts from all signatures
