Utilities: Allow for white spaces in lsof name parsing
Previously lsof would crash by incorrectly parsing valid file names
that contain spaces.
For example, established TCP socket file descriptors would cause an
lsof crash:
socket:127.0.0.1:33985 / 127.0.0.1:8080 (connected)
This commit fixes the issue by not parsing for white spaces to set the
file name.
