[baseimage] add ipintutil in sudoer file (#6845)

show ip interfaces is enhanced recently to support multi ASIC platforms in this PR- sonic-net/sonic-utilities#1396 .
The ipintutil script as to run as sudo user, to get the ip interface from each namespace.
Add this script to the sudoer file so that show ip interface command is available for user with read-only permissions
