Further cleanining, switching to static library

-Disable LINTing in test macros with comment // NOLINT
-Enable static analyzers for c++ tests
-Switch app4triqs_c to static library
 Dynamic was pickung up previously installed libapp4triqs_c.so in tests
 Also there is no need to be dynamic for applications
-Fix previous change in HeaderFilterRegex:
 'app4triqs/c++' was blocking all headers for clang-tidy checks.
 'app4triqs' works well, but we cannot install any other headers into
 app4triqs folder structure.
 We thus had to create INSTALL_DIR in travis.yml
