Work around weird false positives with cppcheck-2.9.1

Commit 89e38f55 "treewide: Fix header includes to build with musl" added
extra #includes to work with musl.  Unfortunately with the cppcheck version
I'm using (cppcheck-2.9-1.fc37.x86_64 in Fedora 37) this causes weird false
positives: specifically cppcheck seems to hit a #error in <bits/unistd.h>
complaining about including it directly instead of via <unistd.h> (which is
not something we're doing).

I have no idea why that would be happening; but I'm guessing it has to be
a bug in the cpp implementation in that cppcheck version.  In any case,
it's possible to work around this by moving the include of <unistd.h>
before the include of <signal.h>.  So, do that.
