Tests: Cover NO_SONAME property for SHARED libraries

This property was added by commit v2.8.9~204^2~2 (Support building
shared libraries or modules without soname, 2012-04-22).  A test for
using the property on MODULE libraries was added by commit
v2.8.9~204^2~1 (Test NO_SONAME property, 2012-04-23).  Add such a test
for SHARED libraries too.
