devel/libee: Fix missing distfile, level up port compliance
Upstreams MASTER_SITES changed, and was no longer serving libee's distfile,
but a redirect instead:
=> Fetched file size mismatch (expected 357116, actual 19835)
Rainer (rsyslog maintainer) graciously made it available again on my
request via Twitter.
While I'm here:
- pet portlint: WARN: Makefile: "USES" has to appear earlier.
- Fix LICENSE (license text body reads LGPL21+)
- --prefix is already set by framework, remove from CONFIGURE_ARGS
Approved by: portmgr (framework compliance)
