sci-ml/lemonade: pin flm.npu_bin on 11.0.0 and 9999

Propagate the 11.5.0-r1 flm.npu_bin config-seed pin to the remaining
versions. 11.0.0 and 9999 carry the identical flm resolver:
find_flm_in_path() consults PATH only when flm.prefer_system is set, so a
bare /usr/bin/flm is invisible by default and lemond reports the NPU
backend "supported but not installed" (and would re-download the flm NPU
runtime). Both defaults.json carry an flm section, so the has() guard
passes.

Same edits as 11.5.0-r1: add the flm npu_bin pin to the jqf block,
system-fastflowlm to the app-misc/jq BDEPEND, and correct the
pkg_postinst elog/ewarn. 11.0.0 is revbumped to r1 (installed content
changes); 9999's elog/ewarn drop the version-specific "11.x" wording
since it tracks HEAD.
