`wasmer inspect php.wat | less` crashes with broken pipe

[marxin]

I noticed that whenever we inspect a non-trivial file piped to less, then if I close the less command with q, I got:

thread 'main' (46578) panicked at library/std/src/io/stdio.rs:1165:9:
failed printing to stdout: Broken pipe (os error 32)
