[OE-core] [PATCH] package.bbclass: Add ASSUME_SONAME variable

[Aymeric Dumaz]

When libraries don't have a SONAME in their section, their name aren't added in
the .list file generated during do_package.
Other recipes are able to build against them but are not able to find them
afterwards, leading to missing dependencies.

For example, with qtbase and proprietary libraries for the OMAP3:
NOTE: Couldn't find shared library provider for libGLESv2.so, used by files:
[...]

This patch add the possibility to manually define a list of librairies that will
be exported in the .list file.
A hack in a lacking-SONAME recipe can be made on package_do_shlibs_append to
copy .list file manually made, but files from others PACKAGES in this recipe
will produce similar warnings during their creation because their name aren't in
the shlib_provider variable.

The darwin_so is not patched because it isn't relying on SONAME.
