[PATCH v2 RESEND] classes/archiver: fix tarball content in "original" mode

["João Marcos Costa" <joaomarcos.costa@bootlin.com>]

When ARCHIVER_MODE[src] is set to "original", a tarball is generated with
the unpacked sources of a given recipe. Prior to it, a tmpdir
(i.e. from tempfile.mkdtemp()) is created and the sources are unpacked inside:

(...)/vim/9.2.0340/archiver-work/tmp8pu2nsck
`-- vim-9.2.0340
    |-- READMEdir
    |-- ci
    |-- lang

This tmpdir, however, ends up being shipped in the deployed tarball:

$ tar -tf vim-9.2.0340-r0.tar.xz
(...)
tmp8pu2nsck/vim-9.2.0340/ci/config.mk.clang-12.sed
tmp8pu2nsck/vim-9.2.0340/LICENSE
tmp8pu2nsck/vim-9.2.0340/.git-blame-ignore-revs
(...)

This can be avoided by pointing to the subdir where the sources are
unpacked, rather than to tmpdir, when calling create_tarball().

The subdir's name can be inferred from 'BP', so we will use
'tmp8pu2nsck/vim-9.2.0340/.' instead of 'tmp8pu2nsck/.' as input.

e.g. and in the result:

./
./vim-9.2.0304/
./vim-9.2.0304/SECURITY.md
./vim-9.2.0304/.codecov.yml
(...)
