p11-kit >= 0.23.6 assertion error on 32bit big endian

[Andreas Metzler]

Hello,

p11-kit >= 0.23.6 has a testsuite error on 32bit big endian (e.g.
mips, PowerPC or hppa):
ok 12 /rpc/byte-value
not ok 13 /rpc/ulong-value
# assertion failed ((CK_ULONG)0x0123456708ABCDEF == val64): (145477103 == 4294967295)
# in test_ulong_value() at test-rpc.c:436
ok 14 /rpc/attribute-array-value

I have bisected the issue:

    rpc: Convert attribute value for portability

    When using the RPC across multiple architectures, where data models
    are different, say LP64 vs ILP32, there can be unwanted truncation of
    attribute values.

    This patch converts the values into portable format for the known
    attributes.
