procutil: move stdin assignment outside of try-finally block

There is an stdin variable in the global scope of this module. And in the
`finally` block of this try-finally statement we're checking `if stdin is not
None`.  Let's make sure we don't confuse code check tools into thinking we want
to use global stdin by moving this line of code outside of `try`.

This was caught by pytype 2023.11.21 on Python 3.11.2.

#
# wait up to TIMEOUT seconds until a WAIT_ON_FILE is created.
#
# In addition, this script can create CREATE_FILE once it is ready to wait.

if [ $# -lt 2 ] || [ $# -gt 3 ]; then
    echo $#
    echo "USAGE: $0 TIMEOUT WAIT_ON_FILE [CREATE_FILE]"

timer="$1"

# Scale the timeout to match the sleep steps below, i.e. 1/0.02.
timer=$(( 50 * $timer ))
# If the test timeout have been extended, also scale the timer relative
# to the normal timing.
if [ "$HGTEST_TIMEOUT_DEFAULT" -lt "$HGTEST_TIMEOUT" ]; then
    timer=$(( ( $timer * $HGTEST_TIMEOUT) / $HGTEST_TIMEOUT_DEFAULT ))

    timer=$(( $timer - 1))

if [ "$timer" -le 0 ]; then
    echo "file not created after $1 seconds: $wait_on" >&2
    exit 1
