umoven: detect invalid addresses

Do not silently truncate tracee addresses to current_wordsize.
After transition from long to kernel_ulong_t there should be no sign
extension issues with tracee addresses, and invalid addresses should
be printed properly.

* util.c (umoven): Check [SIZEOF_KERNEL_LONG_T > 4] instead
of [SIZEOF_LONG > 4], reject addresses that do not fit into
current_wordsize.
* tests/umoven-illptr.c: New file.
* tests/umoven-illptr.test: New test.
* tests/.gitignore: Add umoven-illptr.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(DECODER_TESTS): Add umoven-illptr.test.
