SWDEV-258808 - OCLSeparateCompile subtest of oclcompiler error

[PAL to KFD/ROCr][ROCr_Runtime][Vega10] OCLSeparateCompile subtest of
oclcompiler from ocltst test package is encountering clLinkProgram()
failed (chksum 0x00000001) error

If runtime does not provide a file name as dump file to ELF library,
ELF library use a temp file in current folder.
The current folder can be not writable for several reasons:
1. The application current folder might be system folder, the user
  does not have write permission.
2. The current folder is under a readonly file system. This happens for
embedded customers.

Tested in VEGA10. Issue was fixed.
