Updated git submodules

Project: releng/builder master f1ca9d0ff0e189bc0c98831417e5b371ec033e16

Fix issue caused by process substitution on sh

The change fixes the issue 'syntax error near unexpected token `<''
which is caused because the while loop and find uses process
substitution feature which is not standard on all shells. The
default shell used to run a builder is 'sh'. To fix the issue
invoke the code from a script using bash.
