We do not strip out fc files that we do not support.  The way the make 
file and hence the RPM works is it looks for *.te files in the 
domains/program directory and uses those names to choose the 
file_context files.  We want to use the same policy source pool to
supoort targeted, strict, mls ... policy.  And therefore get the best 
bang for the buck from the open source community.  So think of the
policy-src files like you do kernel sources.  Just because there is 
stuff in there does not mean we support them.

How about adding
chcon -R -t httpd_sys_script_ro_t /var/log/nagios

Then you don't need to change policy at all
