[PATCH] libgo: Avoid clobbering shell history file in signal_cgo_test.go

[Andreas Schwab]

For some reason signal_cgo_test.go needs to run an interactive shell,
but suppresses reading the startup files.  This causes the shell history
file to be clobbered, by using different history settings than usual.
Avoid that by setting HOME to / so that the shell cannot write a history
file.

        * libgo/go/os/signal/signal_cgo_test.go: Set HOME to / before
        starting shell.
