x11vnc: fix the endian issue in mips for bug 782

x11vnc use LIBVNCSERVER_WORDS_BIGENDIAN to handle the endian, however
it is not set correctly when cross-compile for mips, thus x11vnc mips
does not work correctly.

meanwhile, x11vnc has the autconf macro AC_C_BIGENDIAN which can
handle the endian correctly. so this patch replace the
LIBVNCSERVER_WORDS_BIGENDIAN with WORDS_BIGENDIAN (generated by
AC_C_BIGENDIAN) to fix this issue.

this patch fix the bug [YOCTO #782]

+libvncserver: replace LIBVNCSERVER_WORDS_BIGENDIAN with WORDS_BIGENDIAN
+
+since macro AC_C_BIGENDIAN is used in autoconf and WORDS_BIGENDIAN is
+automatically set for different arch, it is better to use WORDS_BIGENDIAN
+instead of LIBVNCSERVER_WORDS_BIGENDIAN, which cuase issue in mips.
