Symbolic link resolution can be expensive. In our case,
the symbolic links are legacy links to automounts, and
the "file" task was causing all of the legacy links to
be traversed and mounted on every host every time the
task executed, even when the links were correct and there
was nothing to do.

This change avoids the system calls that perform the
symbolic link resolution by taking advantage of the short
circuit behaviur of the boolean "and" operator. The code
behaviour is unchanged except that it no longer performs
unnecessary system calls.

As it turns out, this change is not sufficient to fully
solve the symbolic link resolution problem, as the "file"
module still performs a stat() at the end of execution to
provide the caller with information about the file.
However, this change is very simple, it will eliminate
unnecessary system calls in a number of use cases, and it
gets the "file" module closer to the desired end result.
