Title:
  Setfont error due to deprecated PIO_FONTX ioctl

Status in subiquity:
  New
Status in kbd package in Ubuntu:
  Fix Committed
Status in kbd source package in Jammy:
  New

Bug description:
  There is an error message that get thrown in in syslog.
  There is a suggestion to fix by upgrading the KDB package to version 2.5.1+ or 
  to understand the root cause and troubleshoot as to why it's broken and resolve 
  it there.

  It is caused by this line in subiquity
  https://github.com/canonical/subiquity/blob/46f671d14d57a5da6bc3d60b1da6715b43954f0d/bin/subiquity-service#L11

  It's due to PIO_FONTX ioctl removed from kernel since 5.12
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ff2047fb755d4415ec3c70ac799889371151796d

  In 2.4.5 of kbd which provide setfont in user space, they already
  switched over to use KDFONTOP only.
