[CWB] Micro-bug in install-scripts/install-linux

[José Manuel Martínez Martínez]

I spotted a typo in cwb code. The `install-scripts/install-linux` was
giving me an error message due to a missing quotation mark in line 62:

-    echo "You should use manual installation  with 'make' instead
(see file INSTALL).
+    echo "You should use manual installation  with 'make' instead
(see file INSTALL)."

This fixes the problem.

Cheers,
