Subject: [PATCH] Fix combined usage of BISECT_REVERSE and BISECT_SKIP

When BISECT_REVERSE and BISECT_SKIP are used together with boot or test testing,
build failures are treated as boot or test failures and 'git bisect bad' is executed instead
of 'git bisect good'. This is because the $ret value of -1 is treated as a build failure, but
the $reverse_bisect logic does not properly handle this.

Simple fix, don't invert $ret if it is -1.
