Avoid hardcoded paths in scripts

[nylander]

The acetoscan script has a number of lines where files are written to hardcoded paths. For example (there are several, similar cases):

    exec > >(tee -a "/home/${user}/acetoscan/"acetoscan_log )
    exec 2> >(tee -a "/home/${user}/acetoscan/"acetoscan_log >&2)

The presence of the folder /home/${user}/acetoscan/ should be avoided, and the output files written to a(nother) folder, which can be created at run time.
