cros lint: Run shellcheck in script's directory

Shellcheck can follow source lines to see included files, but it assumes
paths are relative to $PWD.  We can make this consistent by always doing
a chdir to the directory containing the script before running it.  This
lets script authors use "#shellcheck source=..." directives and have
them work regardless of where cros lint is run from.

cros lint runs multiple checks in parallel, but it runs them in separate
processes, so this should still be safe.

In shellcheck 0.7, we'll be able to pass "-P SCRIPTDIR" to achieve the
same effect without a chdir.
