LU-3906 tests: use df instead of lfs_df in run_compilebench()

Since run_compilebench() will be run on NFS client which has no
Lustre filesystem, we need change to use df instead of lfs_df to
get the space usage information.

Test-Parameters: envdefinitions=SLOW=yes,ONLY=compilebench \
testlist=parallel-scale,parallel-scale-nfsv3,parallel-scale-nfsv4
