compiler/clang: ignore main-return-type warning for clang

Unlike gcc, clang splits out the flag controlling warnings about the return type of `main' from other warnings related to that function. Add the extra -Wno-main-return-type flag to mask these warnings when building Zephyr without -ffreestanding, as when using picolibc. Signed-off-by: Keith Packard <[email protected]>
