check: unbreak iam

I don't know why this change was made:

iam=check

to

iam=check.$$

The only users of this variable are:

check:36:iam=check
check:52:rm -f $tmp.list $tmp.tmp $tmp.grep $here/$iam.out $tmp.report.* $tmp.arglist
common/btrfs:216:               if [ "$iam" != "check" ]; then
common/overlay:407:             if [ "$iam" != "check" ]; then
common/rc:3565: if [ "$iam" != "check" ]; then
common/xfs:1021:                if [ "$iam" != "check" ]; then
new:9:iam=new

None of them were ported to notice the pid.  Consequently,
_check_generic_filesystem (aka _check_test_fs on an ext4 filesystem)
failing will cause ./check to exit the entire test suite when the test
filesystem is corrupt.  That's not what we wanted, particularly since
Leah added a patch to repair the test filesystem between tests.
