devserver: ignore time stamps when extracting files with tar
Current 'tar' func in common_util will unzip files with timestamp when the
files' modified time is faster than devserver itself:
command: tar xf tmp.tar.gz --directory ./ --verbose --gzip
output: control.npo_delta_tmp
tar: control.npo_delta_tmp: time stamp 2016-11-11 00:00:00 is
832281.031926535 s in the future
During devserver staging, such output will be written to a marker_file, which
is used by devserver to check whether files are successfully downloaded and
unzipped. If the output includes such timestamp, it's actually not a real file
name, which leads to devserver failing to check whether this file exists, and
claim a false negative stage failure.
This CL changes the tar command to set all of the modified times on the
unpacked files to the current system time.
Also fix lint errors.

TEST=Create a future file, zip it, and then call common.util.ExtractTarball()
to verify.
