fixup &layoutfile reference in fv_southern_tutchone.kmn

Regarding my other comment on the pull request about renaming files

Suggested change

	store(&LAYOUTFILE) 'fv_southern_tutchone.keyboard_info'
	store(&LAYOUTFILE) 'fv_southern_tutchone.keyman-touch-layout'

[darcywong00]

Thank you for the keyboard submission!

There's some cleanup of filenames as follows:

fv_southern_tutchone:
a. delete source/fv_southern_tutchone.keyman-touch-layout
b. rename source/fv_southern_tutchone.keyboard_info to source/fv_southern_tutchone.keyman-touch-layout
c. fixup &layoutfile reference in fv_southern_tutchone.kmn
d. ask FV team to verify the touch layout is correct.
