    net-im/libsignal-node: Fix build on FreeBSD 12.x and 13.x
    
    Limit _XOPEN_SOURCE to Linux as it breaks FreeBSD build.
    This is an import of an upstream patch:

+
+Limit _XOPEN_SOURCE to Linux.
+
+POSIX feature macros are a mess. Reportedly, FreeBSD also breaks with
+_XOPEN_SOURCE, so try leaving it unset by default.
+
+Update-Note: It's possible this will break yet another obscure UNIX.
+Hopefully we can eventually find a combination that works?
