shell: tweak bkslash_in_varexp.tests, add bkslash_in_varexp1.tests
...
It turns out bkslash_in_varexp.tests was a bash bug :]
ash and hush fail "corrected" bkslash_in_varexp.tests as well,
just not as badly as I thought (hush gets half of the cases right).

ash: bash-compatible $'...' shouldn't expand in double quotes
...
Bash doesn't expand its $'...' construct in double quotes:
$ echo "$'a\tb'"
$'a\tb'
Change BusyBox ash to do the same. This also fixes a problem with
here documents where BusyBox ash gave an incorrect result for:
$ cat <<EOF
> '$'
> EOF
'$'
