Subject: [PATCH] Disable unnecessary sanitizers

Clang memory sanitizer needs all linked libraries (including STL) to be
compiled with msan option, otherwise analysis results are practically
unusable.

GCC undefined behaviour sanitizer analysis is already covered by build
running UASAN (undefined behaviour and address sanitizers).
