omusrmsg: don't overwrite previous set _PATH_DEV value

Browse Source 
Since commit 56ace5e418d149af27586c7c1264fccfbc6badf1, omusrmsg was broken
because "memcpy()" is not a suitable substitute for "strncat()" in this
context, it is actually replacing the previous added content.

Bug: https://bugs.gentoo.org/673004
Closes: https://github.com/rsyslog/rsyslog/issues/3346
