Fix regexp expressions in sancov.py to work with old grep on Tizen

Grep is known to treat "\s" differently:
only in newer versions it is intrepreted as whitespace.
See http://savannah.gnu.org/bugs/?30515 for details

On Tizen the grep verions is 2.5.2 and "\s" is not yet supported as a special
symbol there.
