do not shell-quote filenames for environment

This allows dtas-player to play files with wonky filenames
when piping ffmpeg (or avconv) to sox.  SoX-only code
dtas-player paths are not affected since they don't require
an extra Bourne shell.

All of our internal shell pipelines quote "$INFILE",
anyways, so there was never any need to escape for those.

This may cause compatibility problems for splitfx users, but
splitfx is probably too esoteric to have any users besides
myself.  And I expect anybody editing audio with dtas-splitfx to
pick shell-friendly filenames.

dtas-player is far more general, and likely to encounter
shell-unfriendly filenames which require quoting.
