[PATCH] [BUILTIN] Fix corruption of reads with byte 0x81

[Alexey Gladkov <gladkov.alexey@gmail.com>]

Starting with commit 55c46b dash removes CTLESC bytes ('\x81')
from read sequence. This leads to breakage of some UTF8
characters. Like in commit f8231a, this change fixes corruption
by removing the faulty code.

Testcase:

$ /usr/bin/printf '[\u0441]\n'
[с]
$ /usr/bin/printf '[\u0441]\n' |dash -c 'read c; printf "%s\n" "$c"'
[Ñ]
