meson: check if secure_getenv() is present
Not all libc make secure_getenv() available, this could lead to build
failure on certain build systems.
Check if secure_getenv() is available and emit #define
HAVE_SECURE_GETENV to config.h Include config.h to every c/c++ file
during building by adding `-include config.h` to project arguments for
both c and c++.
