opkg-build: Ignore tar error due to hardlinks issue when creating ipk files
If a the number of hard links decreases or increases while creating the tar
files used for an ipk package, tar fails with error code 1, we use hardlinks
on package/ and packages-split/ to decrease disk usage, sometimes other
parts of the build can cause a change in the link count, since this happens
in a controlled environment we can safely ignore the error and continue to
create the ipk file, fixed some typos from old version.
