[OE-core] [PATCH 1/1] meta/lib/oe/utils.py: properly implement both_contain()

[Cristian Iorga]

oe.utils.both_contain() just does a find() on the value
rather than splitting the value and then looking in the
list of split items. The result is that if you add a
feature to MACHINE_FEATURES that itself has a substring
that matches one of the values looked for when building
COMBINED_FEATURES, you end up with an incomprehensible
error (here with "ext2i" in MACHINE_FEATURES):

ERROR: Nothing RPROVIDES 'packagegroup-base-ext2'
(but /home/balister/src/oe-core/oe-core/meta/recipes-core/
/packagegroups/packagegroup-base.bb RDEPENDS on or otherwise requires it)

Fix [YOCTO #6888].
