remove redundant, too-early call to clearenv in api_start call.
Ok, took a look, what happened was the clearenv calls used to be
in lxc_start and lxccontainer and lxc_execute (do lxc_start() callers)
themselves. I moved those into do_start(), but the calls in
lxccontainer.c were never removed.
They should simply be removed altogether. Trivial patch follows.
