s390: gdbarch_tdep.have_* int -> bool

Currently the gdbarch_tdep.have_* flags are a mix of int and bool.  Clean
this up by making them all bool.

gdb/ChangeLog:

	* s390-linux-tdep.c (gdbarch_tdep) <have_linux_v1, have_linux_v2>
	<have_tdb>: Change type to bool.
	(s390_gdbarch_tdep_alloc): Adjust.
	(s390_gdbarch_init): Adjust.
