Agniva De Sarker 8ea45f9674 blog: show a helpful error for invalid template directory
Currently, if the blog binary is executed outside the root directory
without any additional flags, it bails out with the following error -
"open template/root.tmpl: no such file or directory"

This CL prints out a more user friendly error which allows the user to
learn that there is a flag with which the template directory can be set.

Fixes golang/go#22622
