acpi-build: fix build on glib < 2.14
g_array_get_element_size was only added in glib 2.14,
there's no way to find element size in with an older glib.
Fortunately we only use a single table (linker) where element size > 1.
Switch element size to 1 everywhere, then we can just look at len field
to get table size in bytes.
Add an assert to make sure we catch any violations of this rule.
