um: remove uml initcalls
__uml_initcall() is not used and .uml.initcall.init section is empty: $ grep -r '__uml_initcall(' arch/um/include/shared/init.h:#define __uml_initcall(fn) \ $ readelf -s ../umobj/linux | grep __uml_initcall 23214: 00000000603b75d8 0 NOTYPE GLOBAL DEFAULT 32 __uml_initcall_start 25337: 00000000603b75d8 0 NOTYPE GLOBAL DEFAULT 32 __uml_initcall_end So it is unnecessary.
