package/procps: bump version and rename to procps-ng

procps is getting replaced by procps-ng, and there are
new versions available!

procps-ng is now an autotools package, so get rid of our
custom build/install rules.

Remove most patches, except for one that still half-applies,
so update and rename it.

procps is dead, long live procps-ng!
