vtpmmgr: fix build on 32-bit

Correct format string, fixing:
        vtpm_storage.c: In function 'vtpm_storage_load_header': vtpm_storage.c:658: error: format '%ld' expects type 'long int', but argument 5 has type 'unsigned int'
        vtpm_storage.c:658: error: format '%ld' expects type 'long int', but argument 5 has type 'unsigned int' make[2]: *** [vtpm_storage.o] Error 1

Add padlock.o to PSSL_OBJS, fixing:
	/local/scratch/ianc/devel/xen-unstable.git/stubdom/mini-os-x86_32-vtpmmgr/mini-os.o: In function `aes_crypt_ecb': /local/scratch/ianc/devel/xen-unstable.git/stubdom/polarssl-x86_32/library/aes.c:659: undefined reference to `padlock_supports'
