pppd: Fix creation of linkpidfile

When pppd is run without "nodetach" or with "updetach", the linkpidfile is
never created. The call to create_linkpidfile() is protected by a check for
linkpidfile[0] but this is only filled in when create_linkpidfile() is called.

This patch changes to code to allways uncondiationally call
create_linkpidfile(), it originated from the Debian project.
