The IMPORT_PREFIX path in FindHIP.cmake was generated as <Install_Prefix>/hip rather than <Install_Prefix> in Linux OS
With file reorg backward compatibility turned off, the path <Install_Prefix>/hip is no more valid
Corrected the same, so that IMPORT_PREFIX will always be generated as <Install_Prefix>
