Every CPack generator sets default CPACK_PACKAGING_INSTALL_PREFIX
variable value differently so test framework should support
that correctly - previous version expected RPM/Deb /usr default and
removed it for Archive packagers as the default there is /.
Build id links generation was introduced
in rpm 4.13.0.1 so files related to them
should be ignored as they are not relevant
for the tests.
Fixes#16710
Content list for a certain test
should be the same between different
generators so whenever possible use
a single expected files list per
file for all generators.
Each generator generates its own file
format with different extensions but
they all create those file names by
a certain pattern and all of them
require the same pieces for that pattern
to work. Now we can only provide pieces
once and and each generator will use those
pieces to generate an expected file name.
