[OE-core] [PATCH] license.py: remove duplicate '&' or '|' from LICENSE

[Andrei Gherzan]

From: Andrei Gherzan <andrei.gherzan at windriver.com>

Some upstream layers (ex: meta-oe) use '&&' or '||' syntax in LICENSE
variable. Because of my last commit, these bbfiles are failing as LICENSE
is tested with oe.license where '&&' and '||' are the bug source.
The fix is to replace multiple characters of '&' or '|' with a single one.
