Revert r30599 "Check for the magic file "/.rockbox/skin_buffer_size.txt" [...]"

It's not clear whether a user setting is the right/accepted fix for the skin buffer.
But even if it is, this implementation of it is considered bad, even by the author.

See http://www.rockbox.org/mail/archive/rockbox-dev-archive-2011-09/0054.shtml
