CROSSCOMPILE_OPTS is a USE_EXPAND of a single item: headers-only.
Convert it to a global USE flag instead.

The changes are:
- mechanical ebuild rename (touches libcs and kernel headers):
    $ sed -e 's@crosscompile_opts_headers-only@headers-only@g' \
        -i $(git grep -l headers-only)
- added global 'headers-only' USE
- CROSSCOMPILE_OPTS USE_EXPAND is removed

'headers-only' flag is used by crossdev to bootstrap stage1 compiler
before libc is available.

crossdev switched to USE=headers-only in =sys-devel/crossdev-20171230.
After crossdev goes stable this change can go in.
