ipfs: avoid warning during build when moving directory
ipfs: avoid warning during build when moving directory

Trying to move a directory into itself will result in a warning:
mv: cannot move 'ipfs-src' to a subdirectory of itself, 'ipfs-src/ipfs-src'

This can be prevented by excluding that directory.
