The logpipe fifo can remain when exiting on a non-error condition such
as recieving signals INT and USR1.  This can be seen by doing either a
manual CTRL-C to interrupt the build or by sending a signal such as:

$ makepkg & sleep 5 ; kill -USR1 $!

Remove the fifo in all cases on script exit if it still exists.
