Just discovered this while looking at
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241932. ccache
started failing as a result of this change; more investigation is
still necessary.

In any case /proc is deprecated; the canonical way to do this is via
the KERN_PROC_PATHNAME sysctl, as in
lldb/source/Host/freebsd/Host.cpp. I'll post a patch for review in a
bit.
