[oe] [meta-networking][PATCH] snort: fix compile-host-path QA issue

[Yi Zhao]

The Fedora 28+ does not have inbuilt SunRPC support in glibc and is
separately availble in tirpc package. So it enables tirpc checking for
fedora in configure.

Drop this piece of code since we had specify '-ltirpc' in LDFLAGS
explicitly. Otherwise it will cause a compile-host-path QA issue if the
host is Fedora 28+:
cc1: warning: include location "/usr/include/tirpc" is unsafe for
cross-compilation [-Wpoison-system-directories]
