Bug#547073: sysvinit: init should not clear utf8 flag

[Samuel Thibault]

Package: sysvinit
Version: 2.86.ds1-65
Severity: normal

Hello,

init sets c_iflag from scratch. This however clears the IUTF8
flag that the kernel sets according to the vt.default_utf8 kernel
option, resulting to odd behavior of backspace applied to non-ascii
characters. Just like c_cflag flags, init should not clear it, see
attached patch.

Samuel
