[Toybox] [PATCH] Fix od output format when using only legacy type specifiers

[Samuel Holland]

Toybox had been adding the default "oS" output format unless an explicit 
-t option had been given, even if one of the legacy shortcut options was 
given.

This behavior broke building busybox with CONFIG_FEATURE_COMPRESS_USAGE 
as it uses "od -v -b" in applets/usage_compressed
