[Buildroot] [PATCH v3 1/1] utils/check-package: add a check for the new spacing convention

[Heiko Thiery]

The seperation of the fields in the hash file should be 2 spaces for
consistency.

v1 -> v2:
  removed re.escape()

v2 -> v3:
  re-add re.escape and removed '^' and '$' from regexp because they also are
  escaped by re.escape().

  Now 'make check-package' will not throw any exceptions.

  After conversion all hash files to the right format no more warnings
  will occure:

  Oneliner provided by Yann will do that job:
  $ find . -type f -name '*.hash' -print0 |xargs -0 sed -r -i -e 's/^(md5|sha(1|224|256|384|512))[[:space:]]+([^[:space:]]+)[[:space:]]+(.+)$/\1  \3  \4/'
