slurpfile: use lseek() on character nodes instead of fstat() for file size

fstat() is used to determine the filesize before read() and
it requires a filesystem. That means that it can not be used
on character nodes. This makes it impossible to obtains the
kernel from a char node like mtd or more likely ubi.
We can't use this in every case because files in /proc don't
support lseek(). This is required by the powerpc part to read
some device-tree entries.
