[rfa/testsuite/mi] Fix transient failures in mi*-hack-cli.exp

[Daniel Jacobowitz <drow@mvista.com>]

This one was a real nuisance to find...

mi_gdb_test expects strings without the trailing newline.  If there is a
trailing newline, we'll get two prompts back.  In some cases, depending on
the delicacy of timing, this can cause a problem.  The output looks like:

47show architecture

&"show architecture\n"
~"The target architecture is assumed to be i386\n"
47^done
(gdb)
&"\n"
^done
(gdb)


As best I can tell, this hits a bug (feature?) in the regular expression
matcher involving greedy matches.  The .*" sequence in the test matches from
the beginning of ' is assumed' all the way down to the second '&"\n"'.  Thus
the ^done bit does not match successfully.

Removing the unnecessary newlines masks the bug, as best as my tests can
tell.  OK to commit?

	* gdb.mi/mi-hack-cli.exp: Remove excess newlines from test strings.
	* gdm.mi/mi0-hack-cli.exp: Likewise.
