sys-(devel|libs|kernel),profiles: make upstream gdb work, add gcc-9.3.0 changes

This PR includes the necessary changes to upgrade the SDK compiler to gcc-9.3.0.
It also changes the gdb-9.2 recipe to work with the Flatcar SDK.

The changes include:

sys-devel/gdb/gdb-9.2.ebuild: use EAPI6 to work around BDEPEND emerge bug
update sys-libs/nss-usrfiles to nss-usrfiles-2.30.ebuild to support glibc > 2.29
update sys-kernel/README.md to call out need for updating kernel-headers, perf
add sys-libs/glibc/README.md outlining our changes to the glibc recipe
update profiles/coreos/base/package.accept_keywords to include new toolchain

The change also adds a README to
sys-libs/glibc/README.md
and it improves on a README in
sys-kernel/README -> sys-kernel/README.md

# Fatcar Container Linux kernel packages

The coreos-firmware package is a magic version of the upstream

# GLibc
The system's C library, sometimes referred to as "service pack for the C
language". The build recipe has a single modification over the one Gentoo
upstream uses: in the installation callback `glibc_do_src_install`, we remove
all of glibc's `/etc` files right after the stock glibc build diligently
installed them, since we ship our own `/etc` stuff via the `baseimage` recipe.
The addition sits at the end of the `glibc_do_src_install` function and is duly
labelled `## Flatcar Container Linux: ...`.
