watchpoint.exp: Remove hpux cruft.

[Pedro Alves <palves at redhat dot com>]

These warnings are nowwhere to be found in gdb's codebase.

 - warning: can't do that without a running program; try \"break main\", \"run\" first

 - Target does not have this type of hardware watchpoint support

So I'm being bold and simply removing the hpux specific dead tests.

2012-01-26  Pedro Alves  <palves@redhat.com>

	* gdb.base/watchpoint.exp (wp_set): Delete.
	(initialize, test_simple_watchpoint, top level): Remove dead code.
