[rfc][jdk7] jhat manpage have corrupted url in see also.

[Jiri Vanek]

hi!

jhat.1  have wrong url in "see also" section in openjdk7 [1]

Jdk 8 and 9 have this url correct.

Attached patch is fixing it: https://jvanek.fedorapeople.org/oracle/jdk7/webrevs/jhat.1/v1/

I do not have commit access, so please if anybody can review and push, I will be happy. It is also 
unifying dots on end of this affected lines

I'm not sure if jdk7u or this one is more correct list. But if this one is at least bit correct....

TY!
  J.
