hw/i386/fw_cfg: Use g_new() and g_new0() instead of g_malloc()

Replace g_malloc() and g_malloc0() calls that calculate the allocation
size using sizeof() with the type-safe g_new() and g_new0() macros.

This aligns the code with QEMU's coding style guidelines, improving
readability and protecting against potential integer overflow
vulnerabilities when allocating arrays.
