Avoid the macOS API ccache in forked children
The macOS API ccache module communicates with the credential cache
service through the CCAPI framework and XPC. In a child process
forked from a parent that already used them, those calls can crash the
process. Record the pid of the first API ccache use; in a child
forked after that, report the API collection as empty, treat caches as
not found (KRB5_FCC_NOFILE), and leave CCAPI objects inherited from
the parent unreleased, so the child never calls the CCAPI framework or
XPC.
