[Skiboot] [PATCH] pflash and opal-prd: Fix dist-clean

[Breno Leitao]

Currently pflash and opal-prd do not return to its original tree
after a 'make distclean'. I understand that distclean should return the tree to
its original state, so, the make can restart from scratch.

On Debian[1], we need to clear these remaining file 'manually' to make the
build 'reproducible' (two builds in sequence).
