[PATCH] sbuild: Replace getpid with task hash

[Anton Mikanovich <amikan@ilbers.de>]

To be sure there are no issues with SBUILD_CHROOT value generation
caused by inline getpid execution use BB_TASKHASH instead.
This variable holds the hash of the task filled by Bitbake and should
have the same level of uniqueness as pid inside one build.

This change may help to fix sporadic sbuild session mismatch issue.
