profiles: unset USE=session in default/linux/make.defaults.

The "session" USE flag has been enabled by default for all linux
profiles in default/linux/make.defaults since 2010. According to the
comment in that file, the flag was added for dev-lang/php where
session support is near-critical. But, now that we have an IUSE
default, the global setting is redundant.

This commit drops USE=session from the default/linux profile's
make.defaults, and also drops the (now unnecessary) override of that
flag in the features/hardened profile's make.defaults.

A few other packages with "session" in IUSE will be affected by this
change; however, the meaning of "session" varies wildly between the
packages that use it. Since the meaning of "session" is dependent on
the package in question, within the package itself (that is, with IUSE
defaults) is a better place to enable this flag by default.

Closes: https://bugs.gentoo.org/635742
