fat: correct sign for deletion mark

The FAT file systems uses character '\xe5' to mark a deleted directory
entry. If a file name starts with this character, it is substituted by
'\x05' in the directory entry.

While (signed char)'\xe5' is a negative number 0xe5 is a positive integer
number. We therefore have define a constant DELETED_MARK which matches the
signedness of the characters in the directory entry.

Correct a comparison where we used the constant 0xe5 with the wrong sign.
Use the constant aRING instead of 0x05 like in the rest of the code.
