sox: add -Wno-format to CFLAGS

This is an update to commit 9a95842.
Silence format warnings originating from usage of PRIu64
and PRIuPTR within lsx_warn, lsx_debug and lsx_fail, e.g.:
  warning: unknown conversion type character 'l' in format [-Wformat=]
  warning: too many arguments for format [-Wformat-extra-args]
