sys-libs/musl: add warning to /etc/env.d/00musl

env-update relies on this entry (which populates LDPATH) to look in
/etc/ld.so.conf.d/* which is needed to find GCC libraries.

Add a header reading the following:
> 00musl autogenerated by sys-libs/musl ebuild; DO NOT EDIT.

Prompted by a case on IRC where a user overwrote the file when following
a wiki page, see:
* https://wiki.gentoo.org/index.php?title=Musl_usage_guide&diff=1310555&oldid=1303905
