training: Add new flag --workspace_dir to tesstraining_utils.sh

Browse Source 
By default, that script creates two new temporary directories with random
names in /tmp.

The new command line flag --workspace_dir PATH uses the given path as
a base directory for all temporary files.

That allows better reproducable training results (no random directory
names in log files).
