rpm: bigger refactor of import-srpm

Import source rpms in the same way as unpacked sources: that is, first
unpack the srpm and then use the same code for importing. Also, tries to
make tmpdir handling a bit better: all temporary directories are created
under one "base tmpdir".

Also, get rid of the orig tarball guessing and unpackging in SrcRpmFile
class in gbp.rpm.
