[PATCH 5/7] filetype: make file type strings optional

[Sascha Hauer <s.hauer@pengutronix.de>]

This adds a new Kconfig option FILETYPE_STRING which makes
printing file types as strings optional. The filetype_str[]
array has become quite big and with this we can get rid of
it in size constraint barebox images. Make it default y to
keep the existing default.
