Request for review (trivial): 7008444 Remove unnecessary include of stdint.h in java_md.c

[David Holmes]

The changes for 7006354 added an include of stdint.h in 
src/os/posix/launcher/java_md.c, but this include file does not exist in 
Solaris 8, which is the build platform for JDK6.

The change was investigated and implemented by Bengt Rutisson, but as 
he's now on vacation I'm doing the push with Bengt as one reviewer.

Tested via JPRT builds for different release trains.

Thanks,
David Holmes
