Rename Solaris's target to "target child" like most other ports.

Rename Solaris's target to "target child" like most other ports.

Note that "target procfs" is used by QNX, but the test must be failing
there, as nto-procfs.c overrides to_open with a method that doesn't
throw the error being tested.  So I'm just removing the test
completely.

	* procfs.c (procfs_target): Don't override to_shortname,
	to_longname or to_doc.

	* gdb.base/default.exp: Don't test "target procfs".
