RFR [XS] : 8227630: adjust format specifiers in loadlib_aix.cpp

[Baesken, Matthias]

Hello, please review this very small fix for AIX .

Currently we use %llu printf-format specifiers at 2 places in loadlib_aix.cpp where we output size_t variables .
This leads to warnings with xlc16/xlclang :

/nightly/jdk/src/hotspot/os/aix/loadlib_aix.cpp:210:48: warning: format specifies type 'unsigned long long' but the argument
has type 'size_t' (aka 'unsigned long') [-Wformat]
  trcVerbose("loadquery buffer size is %llu.", buflen);
                                       ~~~~ ^~~~~~
                                       %zu

We can use correct format specifiers (casting might be another option).
