Subject: Add remove-inferiors test

I noticed that the remove-inferiors command was not tested, and as I am
doing some changes related to the user selection, I want to make sure I
don't break it.  For example, I want to make sure it's not possible to
remove the current inferior.

gdb/testsuite/ChangeLog:

	* gdb.multi/remove-inferiors.exp: New file.
	* gdb.multi/remove-inferiors.c: New file.
