[Toaster] [PATCH 7/7] toaster: unlock BuildEnvirnoment when build is done

[Ed Bartosh]

There is no need to lock build environment before changing
build status as this operation is very fast. However, there
is a need to unlock it after changing build status.

Explicitly unlocked BuildEnvironment after build reaches
final status SUCCEEDED, FAILED or CANCELLED. This should
allow runbuilds process to pickup next build faster.
