Tweak recipetool and devtool to correctly use UNPACKDIR. This allows some simplification of the code. This patch makes things basically work but there are likely deeper improvements that can be made now that WORKDIR != UNPACKDIR. (From OE-Core rev: d2eeaa88b27a2875c419591d1d91bcc85d7b129c) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
