[hostlogger] Trailing LF is dropped from host logger to rsyslog

[Heyi Guo]

Hi Spencer,

Thanks for your info; I check my configuration file and it is almost the 
same with the one you post, except for below items:

- SysSock.Use="off"

- UseSpecialParser="off"

- ParseHostname="off"


However the trailing LF of each transfer is still dropped in the target 
file.

Any other ideas?

PS: We are using the version of rsyslog from openbmc 2.10.0-rc1.

Thanks,

Heyi
