Update omapresent to 0.1.1

Picks up the audience-window fix released in v0.1.1: the audience view is now
an independent native Wayland top-level, so a compositor or share portal can
offer it on its own instead of only exposing the editor window. Without it,
screen sharing a deck on a call does not work correctly.

pkgver carries the source URL, which interpolates it, so the package now builds
the immutable v0.1.1 tag archive. The checksum is that archive's sha256.
