pam_namespace: close unnecessary file descriptors before exec()
Currently the `rm` subprocess and the namespace init script inherit a
random set of open file descriptors from the process running PAM.
Depending on the actual PAM stack configuration these can even be
security sensitive files. In any case it is unclean to inherit
unexpected open file descriptors to child processes like this.
To address this close all file descriptors except stdio before executing
a new program.
