[PATCHv2] kbd: make libkbdfile-test08 ptest work for multilib

["Mingde (Matthew) Zeng" <matthew.zeng@windriver.com>]

This patch fixes kbd ptest libkbdfile-test08 failure in 64-bit images.

```sh
root@intel-x86-64:/usr/lib64/kbd/ptest# ./run-ptest
make: Entering directory '/usr/lib64/kbd/ptest/tests'
make[1]: Entering directory '/usr/lib64/kbd/ptest/tests'
PASS: libkbdfile-test01
PASS: libkbdfile-test02
PASS: libkbdfile-test03
PASS: libkbdfile-test04
PASS: libkbdfile-test05
PASS: libkbdfile-test06
PASS: libkbdfile-test07
FAIL: libkbdfile-test08
PASS: libkbdfile-test09
...
```

`DATADIR` and `ABS_DATADIR` are compile flags defined in
./kbd/tests/Makefile.am. `DATADIR` is the relative directory of
kbd, i.e `./kbd/ptest/tests` whereas `ABS_DATADIR` is the full
directory path, i.e `/usr/lib/kbd/ptest/tests`. The latter has a
problem when building ptests for a 64-bit image, because the tests
folder is located at `/usr/lib64/kbd/ptest/tests` instead.

Therefore `ABS_DATADIR` is changed to `DATADIR`, also consistent with
what *every other* kbd test is doing.

The test searches DATADIR recursively for a file named `test0.map`,
but it finds the wrong file at
    `/findfile/test_0/keymaps/test0.map`,
while it actually needs
    `/findfile/test_0/keymaps/i386/qwerty/test0.map`.

Thus appending `/i386` to `dirpath` so that `libkbdfile-test08.c`
    finds the right test file.

+Subject: [PATCH] Use DATADIR and append i386 to fix libkbdfile-test08 ptest
+ failure
+
+Replace ABS_DATADIR with DATADIR and append i386 to dirpath.
+
+Upstream-Status: Inappropriate [OE specific]
+
+This OE specific patch applies to kbd v2.2.0 for now, the upstream
+made drastic changes since v2.2.0, in fact they got rid of ABS_DATADIR
+in commit 5b6df5c along with a series of other commits which may or
+may not fix this issue. We will find out in future releases.
