Refactor Makefile.

Move the go commands that should run under cmd/ipfs in the Makefile in
cmd/ipfs rather than doing a "cd cmd/ipfs && go ..." in the root
Makefile.

The "cd cmd/ipfs && go ..." lines causes problems with GNU Emacs's
compilation mode.  With the current setup Emacs is unable to jump to
the location of the error outputted by go compiler as it can not find
the source file.  The problem is that the embedded "cd" command causes
Emacs's compilation mode to lose track of the current directory and
thus attempts to look for the source file in the wrong directory.
