Fix TestProcessIO.py when run against a remote target

Fixed test case to copy redirected stdout/stderr files from remote
target to host

llgs wasn't bothering to put the pty master file handle in the right
place if stdout/stderr were redirected to a file. It is still needed
for stdin.

Corrected some log message text
