RFR(S): 8224672: (lib)hsdis-<arch>.so search incorrect after JDK-8213084

[Schmidt, Lutz]

Dear All, 

I would like to request reviews for this little patch, fixing an issue with finding the hsdis disassembler library:

Bug:    https://bugs.openjdk.java.net/browse/JDK-8224672 
Webrev: https://cr.openjdk.java.net/~lucy/webrevs/8224672.00/ 

Tracing the library search locations now shows: 
  Trying to load: <home>/jdk/lib/server/libhsdis-amd64.dylib
  Trying to load: <home>/jdk/lib/server/hsdis-amd64.dylib
  Trying to load: <home>/jdk/lib/hsdis-amd64.dylib
  Trying to load: hsdis-amd64.dylib via LD_LIBRARY_PATH or equivalent
  Loaded disassembler from hsdis-amd64.dylib

~shade: thank you Aleksey for discovering the issue.

Regards,
Lutz
