bitbake: bitbake: ConfHandler: Don't strip leading spaces

Fixed:
- Add the following lines to conf/local.conf:
  FOO = "BAR1"
  FOO_append = "\
      BAR2"

  $ bitbake -e | grep '^FOO'
  FOO="BAR1BAR2"

  The leading spaces in the second line have been removed.

- But if add the previous two lines to base.bbclass:
  $ bitbake -e | grep '^FOO'
  FOO="BAR1    BAR2"

  The leading spaces in the second line are preserved, this is inconsistent, now
  fix ConfHandler to preserve leading spaces.
