btrfs-progs: Makefile.extrawarn: Don't warn on sign compare

Under most case, we are just using 'int' for 'unsigned int', and doesn't
care about the sign.

The -Wsign-compare warning is causing tons of false alerts.  Suppressing
it makes W=1 less noisy so we can focus on real problems, while still
allowing it in W=3 build.
