[virt-tools-list] [PATCH 4/5] make executables work

[Gene Czarcinski]

1. Add virtcli to data_files[]

2. Add code to wrapper created in my_build() to determine
the directory the wrapper script is located and then
execute the python program which is located releative
to that directory.  For real system installs, this
directory will be "/usr/bin".

3. Update virt-manager.spec for the virtcli directory.
