lua: lnum: fix strtoul based number parsing
Lua's LNUM patch currently doesn't parse properly certain numbers as
it's visible from the following simple tests.
On x86_64 host (stock Lua 5.1.5, expected output):
$ /usr/bin/lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)'

On x86_64 host:
$ staging_dir/hostpkg/bin/lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)'

On x86_64 target:
$ lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)'

On ath79 target:
$ lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)'

It's caused by two issues fixed in this patch, first issue is caused by
unhadled strtoul overflow and second one is caused by the cast of
unsigned to signed Lua integer when parsing from hex literal.
Run tested on:
* Zidoo Z9S with RTD1296 CPU (aarch64_cortex-a53)
* qemu/x86_64
* qemu/armvirt_64
* ath79
