package/xdg-dbus-proxy: add patch to support building with musl

Import "0001-Fix-musl-compilation-by-adding-TEMP_FAILURE_RETRY.patch"
from the upstream repository, which allows building against the musl
libc (or any other which does not define the TEMP_FAILURE_RETRY macro).
The patch has been accepted upstream, but no releases have been made yet
which include the fix.
