[PATCH] oeqa/selftest: Fix failure when configuration contains BBLAYERS:append

[Oleksandr Hnatiuk]

When used with `--newbuilddir` option, it replaces relative paths in
BBLAYERS variable with absolute paths by evaluating the final value of
the variable, converting paths and saving result by assignment
(`BBLAYERS =`) at the end of bblayers.conf.

This breaks tests when bblayers.conf contains BBLAYERS:append because
:append statements are evaluated after all assignments and we end up
with the appended layer added twice - first by evaluating final value
of the variable, then again by bitbake evaluating BBLAYERS:append.

The error is as follows:
AssertionError: Command 'bitbake  -e' returned non-zero exit status 1:
ERROR: Found duplicated BBFILE_COLLECTIONS 'layer-name', check bblayers.conf or layer.conf to fix it.
