shell: update HISTFILESIZE code to be actually useful
"HISTFILESIZE=0" in profile wasn't working as intended,
"unset HISTFILE" wasn't preventing creation of history files
Now:
HISTSIZE=n allows to reduce in-memory history buffer
HISTFILESIZE=n allows to reduce history file size (0: truncate it)
unset HISTFILE allows to not save history file at all
