Details:

The pkg function creates empty directories and files in the user's home
directory, or wherever pkg('prefix') and pkg('local_list') are set to, even if
they are not needed.

It shouldn't be too hard to defer creating these files and directories until
they are actually used by a pkg command. There is no reason for 'pkg prefix
/tmp/foo' to actually create the /tmp/foo directory, until a 'pkg install'
command is done later.

Similarly, it shouldn't be an immediate error if I try 'pkg prefix
/root/octave', it should just store that for the next pkg command. Then when I
actually try to install a package in /root/octave, it should error.
