[LTP] [PATCH v4 4/4] generate_lvm_runfile.sh: Fix bashism

[Petr Vorel]

Hi Martin,

Thanks! I'll wait unless you suggest anything on 3rd commit and merge with this
style change below. FYI I tested various setup:

for i in y n 0 1 ""; do
	echo "== '$i' =="
	LTP_COLORIZE_OUTPUT=$i PATH="/opt/ltp/testcases/bin:$PATH" $f
	rc=$?
	echo "'$i': $rc"
	[ $rc -eq 0 ] || break
done

I also added patch for this test

Kind regards,
Petr
