bsdinstall: avoid conflicts with fd 3
Throughout the bsdinstall script fd 3 is used by f_dprintf (set through
$TERMINAL_STDOUT_PASSTHRU). In several places in the bsdinstalls scripts,
we use fd 3 to juggle stdout when calling out to other tools, which can
cause the installer to fail with a "Bad file descriptor" error when
f_dprintf attempts to use it.
This commit replaces all constructs like this:
exec 3>&1
SOME_VARIABLE=$(some command 2>&1 1>&3)
exec 3>&-
With:
exec 5>&1
SOME_VARIABLE=$(some command 2>&1 1>&5)
exec 5>&-
