lib/oe/package: replace in place PN-locale-* packages in PACKAGES

split_locales() removes PN-locale from PACKAGES and adds PN-locale-* to the end.
As the PN-locale package typically appears before PN base package, it may result
in paths not installed in PN-locale-* packages if already catched by PN. Now
insert PN-locale-* exactly where PN-locale was existing in list to avoid such
an issue.
