sys-devel/sysroot-wrappers: Drop as Gentoo's gcc will handle sysroot

Browse Source 
It will patch gcc to respect ESYSROOT when cross-compiling, effectively
adding the --sysroot flag without the use of flags or wrappers. This
hasn't been merged into Gentoo yet, but it has been given the nod. When
it does get merged, it was only be for newer gcc versions than we're
currently using, so we'll need this user patch in the meantime
regardless.

The ESYSROOT patch is pending inclusion into Gentoo's gcc patch set. Once
merged, this will most likely be applied from 14.1 or 14.2 onwards. Check the
[GitHub pull request](https://github.com/gentoo/gcc-patches/pull/3) for the
current situation.
