[Patch] haikudepot/model/PackageActionHandler.h: fix header guard spelling
Fix header guard spelling as clang point out.
/home/haiku/haiku/haiku/src/apps/haikudepot/model/PackageActionHandler.h:6:9: warning: 'PACKAGE_ACTION_HANDLER_H' is used as a header guard here, followed by #define of a different macro [-Wheader-guard]
#ifndef PACKAGE_ACTION_HANDLER_H
^~~~~~~~~~~~~~~~~~~~~~~~
/home/haiku/haiku/haiku/src/apps/haikudepot/model/PackageActionHandler.h:7:9: note: 'PACkAGE_ACTION_HANDLER_H' is defined here; did you mean 'PACKAGE_ACTION_HANDLER_H'?
#define PACkAGE_ACTION_HANDLER_H
^~~~~~~~~~~~~~~~~~~~~~~~
PACKAGE_ACTION_HANDLER_H
Fixed in hrev50402.
