syslinux: fix reinstall error

Fixed:
make: *** No rule to make target `/path/to/sysroot/4.9.0/include/stdarg.h', needed by `cpio.o'.  Stop.
make: *** Waiting for unfinished jobs....
ERROR: oe_runmake failed

This happens when upgrade gcc from 4.9.0 to 4.9.1, and the .cpio.o.d isn't
regenerated when recompile (the compile happens when do_install), the content
of it are:

[snip]
cpio.o: /path/to/sysroot/4.9.0/include/stdarg.h
[snip]

And Makefile includes the .cpio.o.d file if it exists, so there would be
errors when /path/to/sysroot/4.9.0/include/stdarg.h doesn't exist.

Remove .*.d (a few .d files, its Makefile uses this wildcard) will fix
the problem.
