Subject: [PATCH] Sort input file list

so that liblinphone++.so builds in a reproducible way
in spite of indeterministic filesystem readdir order

---
While working on the reproducible builds effort, I found that
when building the linphone package for openSUSE Linux (in disposable VMs),
there were differences between each build,
because ordering of functions in linphone++.cc
depended on the indeterministic filesystem order.
