[PATCH 2/2] qemu: Fix build on 32-bit platforms

[Jim Fehlig via Devel]

Commits c2518f7bc7 and 28a0621528 introduced build failures on 32-bit
platforms by using incorrect format specifiers with g_strdup_printf.

In one case, an 'unsigned long' format specifier is used with a
'long long int' variable. Fix by changing the format specifier to
'uintmax_t', and casting the variable likewise.

In a second case, an 'unsigned long' format specifier is used with a
'size_t' variable, which is 'unsigned int' on 32-bit systems. Fix by
changing the format specifier to use the 'z' modifier.

Fixes: c2518f7bc7dd4f8ab8655a12ec3a000e1eb5b232
Fixes: 28a06215280b99708ed8dc2d183f62ba7b34ccf8

A lot of ways to skin this cat, but I think this would be the
preferred approach. And while adding the 2 'Fixes:' lines to the
commit message, I questioned whether this should be 2 patches.
