local.conf.sample: add PATH to SSTATE_MIRRORS comments
The shared state cache as pointed to by SSTATE_DIR by default now has
two-character subdirectories to prevent there being an issue with too
many files in the same directory; also, native sstate packages will go
into a subdirectory named using the distro ID string. If you copy the
newly structured sstate cache to a mirror location (either local or
remote) and then point to it in SSTATE_MIRRORS, you need to append
"PATH" to the end of the mirror URL so that the path used by bitbake
before the mirror substitution is appended to the path used to access
the mirror.
