[PATCH 9/9] rcutorture: Simplify functions.sh include path

Inclusions of 'functions.sh' from 'kvm-test-1-run.sh' and 'kvm-recheck*.sh' are using its absolute path. Because directory for 'functions.sh' is already in PATH, however, it could be included without the full path. This commit simplifies the inclusions to use simple, short relative path.
