[ptxdist] [PATCH] qemu / 9p: store metadata for / in correct file

[Robert Schwebel]

Since qemu commit 81ffbf5ab1458e357a761f1272105a55829b351e the metadata
for / is not stored in platform-<nnn>/.virtfs_metadata/root but instead
in platform-<nnn>/root/.virtfs_metadata_root.

Without this patch, / belongs to the user+group of the ptxdist user, not
to root+root.
