Port msan_test.cc to NetBSD

[krytarowski]

Summary

The changes allows building this file on NetBSD, mostly by
disabling the unsupported functions and adding OS-specific
system includes.

Could please make it:

#if defined(__FreeBSD__) 
// entire function
#elif defined(__NetBSD__)
// entire function
#elif defined(__GLIBC__)
// entire function
#else
# error "TODO: port this"
#endif

There is an informal tradition to reuse the same code in FreeBSD and NetBSD, ifdefing only the MIB part.

[krytarowski]

lib/msan/tests/msan_test.cc

For example here:

lib/sanitizer_common/sanitizer_linux.cc-#if SANITIZER_FREEBSD || SANITIZER_NETBSD
lib/sanitizer_common/sanitizer_linux.cc-#if SANITIZER_FREEBSD
lib/sanitizer_common/sanitizer_linux.cc:  const int Mib[4] = {CTL_KERN, KERN_PROC, KERN_PROC_PATHNAME, -1};
lib/sanitizer_common/sanitizer_linux.cc-#else
lib/sanitizer_common/sanitizer_linux.cc:  const int Mib[4] = {CTL_KERN, KERN_PROC_ARGS, -1, KERN_PROC_PATHNAME};
lib/sanitizer_common/sanitizer_linux.cc-#endif

I will commit it as is, and on request change it to separated functions.
