IMPALA-11193: Fix assertion failure of ClientCacheTest.MemLeak in CentOS
The assertion failure happens in CentOS because the testcase
reads the virtual memory usage of the current thread from
/proc/thread-self. However, CentOS may not contain this symlink,
therefore the testcase is not able to locate the path and
then triggers the assertion.
This fix changes the path to /proc/self, which is a symlink to the
current process and available in CentOS. Because the testcase
doesn't involve multithreading, it is okay to replace the
/proc/thread-self by /proc/self to detect the memory usage.
Tests:
Passed core tests in CentOS.
