Revert ServerAliveInterval

Revert ServerAliveInterval change in 6.20161111, which caused problems
with too many old versions of ssh and unusual ssh configurations.

It should have not been needed anyway since ssh is supposted to
have TCPKeepAlive enabled by default.

+Could the original bug reporter please show what your ~/.ssh/config
+contains? As far as I can tell, ssh's TCPKeepAlive option, which is
+supposed to be enabled by default, unless you have disabled it, should
+avoid such problems.
+
+It may also help to set ServerAliveInterval.
+
+Unfortunately, my attempt to make git-annex set ServerAliveInterval
+when running ssh broke too many systems with old sshed, and I have had to
+revert it.

 ### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
 
 Yes, it's been taking care of my archives for nearly a year.
