eol: fix update - don't use and apply removed .hgeol patterns

'hg up -C' to revisions with different .hgeol patterns could leave dirty
changes in the working directory. That could make deployment of new .hgeol
filters tricky: they would "occasionally" apply also in branches where they
shouldn't.

Fixed by dropping all old patterns before applying new ones.
