Process umask was unmasking bits on SSD to GPFS file copy on create in GPFS. Reproduced problem. Unit tested change in fh.cc

After discussion, we concluded that the umask settings defined in the systemctld service were the proper controls. The umask is default is also correct - - we didn't want a user to mistakingly set file/directory ACLs with wide permissions on an ephemeral, single-user file system and then those permissions are blindly copied into cluster-wide storage. System admins can override this behavior if they chose. Closing PR.
