Merge pull request #3027 from rmetrich/shrinking_file
In build/GNU/Linux/100_copy_as_is.sh
ensure to really get all COPY_AS_IS files copied by using
'tar ... -i' when extracting to avoid a false regular exit of 'tar'
in particular when padding zeroes get added when a file being read shrinks
because for 'tar' (without '-i') two consecutive 512-blocks of zeroes mean EOF,
cf. https://github.com/rear/rear/pull/3027
