[Tools] Add support for "webKitBranchBuild" git option when calculating jhbuildPath

Currently, ports that use jhbuild fail to determine jhbuild directory when "webKitBranchBuild" git configuration property is enabled. To reproduce that issue in Efl port, enable that flag in .git/config, switch to a git branch other than "master" and try to build webkit. The build will fail to locate dependencies due to lack of pkg-config paths which should be set by jhbuild.

This line is error prone as it depends on the implementation detail that baseProductDir() always appends a "/" to the end of the base product path when it's a Git branch build by line 239 of webkitdirs.pm (r152104), <http://trac.webkit.org/browser/trunk/Tools/Scripts/webkitdirs.pm?rev=152104#L239>. This detail is likely to change as we move towards using File::Spec operations to build a file system path instead of string concatenation to build a path. I suggest that we pop() the last directory only if it's a Git branch build and gitBranch() is a non-empty string.

Yes, you're right. I'll add that checking (non-empty gitBranch()).

thanks
