When using the clearcase plugin on a Unix slave, the CLEARCASE_VIEWPATH variable is set incorrectly using a backslash instead of a slash.

Ex:
WORKSPACE=/workspace
CLEARCASE_VIEWNAME=myview
CLEARCASE_VIEWPATH=/workspace\myview

should be
CLEARCASE_VIEWPATH=/workspace/myview

CLEARCASE_VIEWPATH is set correctly on windows (e.g. %CLEARCASE_VIEWPATH% = %WORKSPACE%%CLEARCASE_VIEWNAME%)

Can work around it by using ${WORKSPACE}/${CLEARCASE_VIEWNAME}, but still should be fixed.
