openssl: Fix failing do_rootfs

* I haven't seen it with webos-image, but with webos-image-devel openssl is
  usually installed before pmcertificatemgr and do_rootfs then fails because
  it cannot replace directory installed by openssl with symlink installed by
  pmcertificatemgr (libpmcertificatemgr2 package)
  * extract_archive: Cannot create symlink from ./usr/lib/ssl/certs to '/etc/ssl/certs': File exists.
  * extract_archive: Cannot create symlink from ./usr/lib/ssl/private to '/etc/ssl/private': File exists.

  The order of installs is not defined because openssl and pmcertificatemgr
  don't have any runtime dependency on each other

  $ grep "Installing \(\(openssl\)\|\(libpmcertificatemgr2\)\)" webos-image-*/temp/log.do_rootfs
  webos-image-1.0-r2/temp/log.do_rootfs:Installing libpmcertificatemgr2 (2.0.0-27-r4) to root...
  webos-image-1.0-r2/temp/log.do_rootfs:Installing openssl (1.0.0j-r15.3webos5) to root...
  webos-image-devel-1.0-r0/temp/log.do_rootfs:Installing openssl (1.0.0j-r15.3webos5) to root...
  webos-image-devel-1.0-r0/temp/log.do_rootfs:Installing libpmcertificatemgr2 (2.0.0-27-r4) to root...

* removed only for target recipe, because we don't have native pmcertificatemgr
