hack/lib/util.sh: replace sed with bash replace.

Test script: #!/bin/bash rev1="foo" rev2="\"bar\"" rev3="'bar'" newrev1="${rev1//[\'\"]}" newrev2="${rev2//[\'\"]}" newrev3="${rev3//[\'\"]}" oldrev1=$(echo "${rev1}" | sed "s/['\"]//g") oldrev2=$(echo "${rev2}" | sed "s/['\"]//g") oldrev3=$(echo "${rev3}" | sed "s/['\"]//g") echo "$newrev1 vs. $oldrev1" echo "$newrev2 vs. $oldrev2" echo "$newrev3 vs. $oldrev3" expected output: foo vs. foo bar vs. bar bar vs. bar
