To avoid repeating detection of fssum presence in many btrfs tests, as
suggested by Dave Chinner.

Also exported the variable "here" from the main control script, to avoid
repeating its declaration in every single testcase file. Also removed the
declaration of "here" from btrfs test cases that require the fssum program
only. Removing it from all other test cases will be a separate change.

Signed-off-by: Filipe David Borba Manana <fdmanana@xxxxxxxxx>

V2: Exported the variable "here" from the main control file, as suggested by
    Dave Chinner. Like this we avoid declaring it again in the new function
    and in many other places.
