lib/oe/terminal.py: use an absolute path to execute oe-gnome-terminal-phonehome

A flaw was found on my Ubuntu 14.04.5 LTS, on which that gnome-terminal is
the default terminal, when I run any of the tasks:
bitbake busybox -c menuconfig/devshell/devpyshell
bitbake virtual/kernel -c menuconfig/devshell/devpyshell

I got a error as follows:
"Failed to execute child process "oe-gnome-terminal-phonehome" (No such file or directory)"

Seems the environment of the process calling Popen is not passed to the
child process, this behaviour is a known issue in Python bug tracker:
http://bugs.python.org/issue8557

It could be fixed by using an absolute path instead per test.
