Revert "Problem with realpath interceptor"
Breaks realpath(, nullptr) for all sanitizers.
Somehow INTERCEPT_FUNCTION and INTERCEPT_FUNCTION_VER return
false even if everything seemingly right.
And this is the issue for COMMON_INTERCEPT_FUNCTION_GLIBC_VER_MIN.
There is a check in every sanitlizer:
if (!INTERCEPT_FUNCTION_VER(name, ver) && !INTERCEPT_FUNCTION(name))
For non-versioned interceptors when INTERCEPT_FUNCTION returns false
it's not considered fatal, and it just prints a warning.
However INTERCEPT_FUNCTION_VER in this case will fallback to
INTERCEPT_FUNCTION replacing realpath with wrong version.
We need to investigate that before relanding the patch.
