Fix a few clang-tidy issues and add NOLINT for others

android-base:
* Add NOLINT for expanding namespace std for std::string* ostream
  overload

libdm:
* Fix missing parentesis around macro parameters

init:
* Fix missing CLOEXEC usage and add NOLINT for the intended
  usages.
* Fix missing parentesis around macro parameters
* Fix erase() / remove_if() idiom
* Correctly specific unsigned char when intended
* 'namespace flags' should be signed, since 'flags' it signed for
  clone()
* Add clear to property restore vector<string> to empty after move
* Explicit comparison against 0 for strcmp

Test: build
