Expand paths to user home directories in connection plugin

This can fail as follows with ansible 2.8:

fatal: [infra1]: FAILED! => {"msg": "failed to transfer file to
/home/zuul/.ansible/tmp/ansible-local-5893pv8hvtki/tmp5likarkj
/proc/548/root/~zuul/.ansible/tmp/ansible-tmp-1582391749.9168267-281064036689686/AnsiballZ_file.py:
mesg: ttyname failed: Inappropriate ioctl for device\ndd: failed to open
'/proc/548/root/~zuul/.ansible/tmp/ansible-tmp-1582391749.9168267-281064036689686/AnsiballZ_file.py':
No such file or directory\n"}

'~zuul' being in the path cuses the failure
