Gabor Juhos d90e805fe6 build: Add TARGET_ROOTFS_RESERVED_PCT option to reduce wasted space 
The genext2fs tool will 'reserve' 5% of the image size by default,
apparently by creating a huge lost+found directory. In fact it seemed to
be much more than 5% in practice — I saw an image with 8MiB used, and
recovered about 2MiB of it by deleting the 'empty' lost+found directory:

/dev/loop0         48377  8482     37438  19% /mnt/spare
 # rmdir lost+found/
/dev/loop0         48377  6014     39906  14% /mnt/spare

This makes it configurable, but leaves it at the genext2fs default
of 5% for now. It should probably be changed to default to zero, but
that can be a separate patch.
