Fix dash bindings on OS X 

Fixes two errors that occur while using Powerline with dash under
Mac OS X.

Problem:  Execution of the mktemp command fails on OS X.
Cause:    mktemp requires a mandatory argument (-t or full path)
Solution: Provide an absolute path as a template to the mktemp command.

Problem:  powerline executable fails to be called because its
          command line unexpectedly contains spaces.
Cause:    The _POWERLINE_JOBS variable contains spaces, because the wc
          command returns spaces before the number on OS X.
Solution: Trim the spaces before assigning the value to the variable.
