configure/ISA-L: Move log file to submodule directory

Running configure script by multiple users on the same machine
leads to access to the same ISA-L log file which is created
with read access for user's group. As the result only the
user who created this file can modify it and other users will
receive "permission denied" error. Move this log file to the
local ISA-L directory to prevent access by multiple users
