tools: drop bogus and obsolete ptyfuncs.m4
According to openpty(3) it is required to include <pty.h> to get the prototypes for openpty() and login_tty(). But this is not what the function AX_CHECK_PTYFUNCS actually does. It makes no attempt to include the required header. The two source files which call openpty() and login_tty() already contain the conditionals to include the required header. Remove the bogus m4 file to fix build with clang, which complains about calls to undeclared functions. Remove usage of INCLUDE_LIBUTIL_H in libxl_bootloader.c, it is already covered by inclusion of libxl_osdep.h. Remove usage of PTYFUNCS_LIBS in libxl/Makefile, it is already covered by UTIL_LIBS from config/StdGNU.mk.
