Rewrite gdb.base/term.exp.

[Pedro Alves <palves at redhat dot com>]

I noticed that the test timeout against extended-remote gdbserver, due to no
inferiorio support.  While fixing that (in order to expose the real missing
feature), I noticed the test could be rewritten in a much simpler form, using
modern mechanisms.

Tested on x86_64 Fedora 16.  Gives one failure against extended-remote gdbserver,

  FAIL: gdb.base/term.exp: info terminal at breakpoint

but that's really expected.

Will apply shortly.
