Separate search for GTEST/GMOCK sources into different cases

Browse Source 
1. If GTEST_ROOT and/or GMOCK_ROOT are defined, sources are expected
somewhere inside these directories. Otherwise a CMake error is
generated. Different source directory layouts are considered.

2. If GTEST_ROOT and GMOCK_ROOT are both not defined, sources are
searched in /usr/src. Different source directory layouts are considered.

3. If sources are not found in one of the first two cases, preinstalled
libraries are searched.

Additionally using HINTS in function find_path() has been replaced by
PATHS and PATH_SUFFIXES. According to CMake documentation in case of
hard-coded guesses PATHS should be used. Remark: This reverts commit
5f53e29, but instead NO_CMAKE_SYSTEM_PATH is used now to prevent CMake
from searching in system paths.

Hint: There was a special handling implemented regarding search for
gmock-all.cc. This file was additionally searched in /usr/src/gmock
directly instead of /usr/src/gmock/src (see commit 1241b71). This
special handling has been kept in case of searching sources in
/usr/src/gmock, but not in case of searching sources in GMOCK_ROOT or
GTEST_ROOT.
