i3-sway: only return current user's socket (#2914)

Browse source 
Constrain the pgrep command to only return results for the current user.
Additionally, quote the socket variables to prevent splitting.

Previously, if multiple users on a system were running `sway`, the
`pgrep` used in finding `swaySocket` would return multiple results. As a
result, reloads of sway would fail.

Fixes #2912.
