All these uwsgi invocations assume that the uwsgi binary is in the
same directory as their project binaries are installed into (probably
/usr/bin). That may not be correct -- for example if using a packaged
uwsgi on Fedora the binary will live in /usr/sbin/uwsgi (not /usr/bin
where the project files from pip are).
Switch invocations to just find it in the path.
NOTE(lyarwood): This change was unfortunatley missing from the original
backport of I82f539bfa533349293dd5a8ce309c9cc0ffb0393 so while uwsgi is
now installed from packages it wasn't actually used. This was only
noticed as g-api was being installed on subnodes in multinode jobs where
uwsgi was not being installed from pip, leading to failures when
attempting to use the project bin path.
