darshan advice conflics with documentation

[roblatham00]

Our docs say

DARSHAN_EXCLUDE_DIRS=<path_csv> | N/A | (DEPRECATED) Specifies a list of comma-separated paths that Darshan will not instrument at runtime (in addition to Darshan’s default exclusion list). Replaced by NAME_EXCLUDE setting.

but if a user parses a darshan log file with lots and lots of entries they will see this advice:

# *ERROR*: The POSIX module contains incomplete data!
#            This happens when a module runs out of
#            memory to store new record data.

# To avoid this error, consult the darshan-runtime
# documentation and consider setting the
# DARSHAN_EXCLUDE_DIRS environment variable to prevent
# Darshan from instrumenting unecessary files.

we should update the advice in darshan-parser to match our own gidance
