Subject: [PATCH 544/584] tests: avoid empty paths in environment variables

Many variables containing paths in env.rc.in are defined in a way
that leave a trailing ':' in the variable when the previous value
was empty or undefined.

In the particular case of 'LD_PRELOAD_PATH' variable, this causes
that the system looks for dynamic libraries in the current working
directory. When this directory is inside a Gluster mount point, a
significant delay is caused each time a program is run (and testing
framework can run lots of programs for each test).

This patch prevents that variables containing paths could end with
a trailing ':'.
