[PATCH] package.bbclass: allow using EXCLUDE_FROM_SHLIBS for subpackages

[Andrii Bordunov <aborduno@cisco.com>]

Some packages containing shared libraries might be registered
as shlib providers when they shouldn't (for example, the lib is for
their private use and must not generate any dependency).

EXCLUDE_FROM_SHLIBS is targeted at that, but it could be set
for entire recipe only.

This patch expands EXCLUDE_FROM_SHLIBS usage, so now it's possible
to set it in a style similar with RDEPENDS. For example:
 EXCLUDE_FROM_SHLIBS_${PN}-ptest = "1"
