[PATCH v2] systemtap: Bump SRCREV for 4.12 Linux kernel support

[Saul Wold <sgw@linux.intel.com>]

This SRCREV bump brings in support for the 4.12 Linux Kernel, this kernel
also has some newer CONFIG settings. The newer DEBUG_INFO and DEBUG_INFO_DWARF4
settings can be used with systemtap to get the full information.  We do not
normally enabled these for a 'production' (standard) kernel, but can be
enabled via menuconfig.

When installing staprun and stapbpf on the target and native ensure we
don't try to create a new group and chown it.  There is no need since we
will be running as root, so we add a patch to comment that code out.

+Since we are in a known environment and installing as root and
+expect to be running as root, don't create the group or chmod
+the binaries.
