[ Upstream commit 1330fc35327f3ecdfa1aa645e7321ced7349b2cd ]

This patch fixes the below warnings with new glibc and gcc:

hv_vss_daemon.c:100:13: warning: In the GNU C Library, "major" 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 "major", include <sys/sysmacros.h> directly.

hv_fcopy_daemon.c:42:2: note: 'snprintf' output between 2 and 1040
bytes into a destination of size 260
