Stefan Berger 3064a72ff0 swtpm_setup: Get rid of 'c' code and support changing user in python
Get rid of the 'c' code that only changed the user and add for support of
the --runas option to change to a different user in the python part.

To get 'make distcheck' to work I needed to name the swtpm_setup python
script with the suffix .in so that it gets copied to the build directory
as swtpm_setup. We need to change execute permissions on this file after
copying.
