udpcast unconditionally build manpages which will raise the following
build failure without pod2man since at least bump to version 20200328 in
commit 4fb91d8b9d:
sh: line 1: pod2man: command not found
To fix this issue, rework how udpcast is built and installed to always
build and install the sender or the receiver and never build the
manpages. As a side effect, this will also avoid to install the unneeded
rateGovernor.h
