Subject: [PATCH] libv4lconvert: fix compiler warning

  CC       control/libv4lconvert_la-libv4lcontrol.lo
control/libv4lcontrol.c: In function ‘v4lcontrol_get_usb_info’:
control/libv4lcontrol.c:391:13: warning: In the GNU C Library, "minor" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "minor", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "minor", you should undefine it after including <sys/types.h>.
       c == '\n' && minor_dev == minor(st.st_rdev))
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Dropped the '#if defined(MAJOR_IN_SYSMACROS)' to ensure that sysmacros.h
is always included. It seems that #if is no longer needed. At least,
nobody complained when I removed it in other places earlier :-)
