Second attempt to make sure starter.sh has o+rx permissions

If starter.sh is missing o+rx on the roboRIO, the robot code will not
start.  If o+rx permissions are missing, there are no error messages on
some driver stations which makes this hard to track down.  Perhaps having
a umask of 0007 on my laptop has something to do with o+rx not being
set explicitly.

Updated starer.sh to properly copy the libstdc++.so.6.0.21 from
local copies of the repsitory not names 971-Robot-Code.h and
added link to the log files.

Tested under Debian stretch by successfully deploying to a newly
flashed roboRIO.

This change was merged into master in commit
ade7810852376a7f70d1c0e0e6f169b2ff4f8e0b on Sat Jan 20 13:56 2018.
It appears that it was removed from master in commit
cb091717cd465dfca867172266b68108c74b8251 by Austin on Wed Feb 21 20:01
2018.  I suspect that this change was inadvertently removed since there
were no comments on why it was removed.
