Typo in section 7 of darshan-runtime docs

[afonsoln]

There seems to be a typo in

darshan/darshan-runtime/doc/darshan-runtime.txt

Line 463 in bddda9d

The only prerequsisite for the APMPI module is that Darsan be configured with a MPI-3 compliant compiler. For APXC, the user must obviously be using a Cray XC system and must make the PAPI interface available to Darshan (i.e., by running `module load papi`, before building Darshan).

where it reads Darsan instead of Darshan.
