Nope.
Errors go to stderr, and output goes to stdout, and never the 'twain
shall meet.
Unless you re-direct in your command with 2>&1 and the shell PHP is
using supports that, which I suspect not.
So then you can write your own shell script that has #!/bin/bash at
the top, which then calls gnomefvs_info (or whatever) but also has the
re-direct of stdout to stderr so you can capture "everything" that
way.

Yes, the Apache user.
Can you su to that Apache user, and create that directory?
Actually, I wonder if ~ is even set as you'd expect...

Write the mini-shell-script suggested above, with that extra bit set
to make it suid or whatever it's called, so it can make the directory
it needs to make.
You could also try to SetEnv('~=/whatever/you/want'); before you do
the exec().
