Remove [d] and [f] from `find` output (closer to unix `find`)

[guicho271828]

Maybe related to #90

this makes it easier to parse rmapi output and build scripts. I am writing a sync command outside rmapi (because it seems easier than learning go myself). related: #148 #134

but find has the -type arg. having [f]/[d] makes filtering easier and just doing | cut -b5- can remove them

[guicho271828]

cut -c5- that is what I am using and replicating the posix behavior is a good thing.
