Problem: pkg-config file cannot be used for static linking on CentOS 7

Browse Source 
Solution: add -lm to Libs.private of libzmq.pc so that the std::ceil
usage in src/decoder_allocators.cpp is satisfied during static linking
on CentOS 7.

See https://github.com/zeromq/libzmq/issues/3710 for a reproducer.
