HAWQ-1529. Fix segment resource manager hang when postmaster died
If PostmasterIsAlive() is under implicit declaration, %eax (32-bits) will
be used for comparison rather than %al (8-bits), BUT PostmasterIsAlive() only
set the lower 8-bits (because 'bool' is really a 'char'). Then segment resource
manager will never exit after postmaster died.
