FAI does not need a tftpd daemon any more, which supports the tsize option

[Thomas Lange]

I just read in the changelog of syslinux-common, that pxelinux 3.70 and
newer versions does not need a tftpd which has the tsize option. Currently
FAI recommends the package tftp-hpa which supports this option, we may
remove this in the future.

>From the changelog of syslinux-common:

 * PXELINUX: We no longer require a TFTP server which supports
   the tsize option for all transfers.
