jscript: Fix GCC 12.2 warning.

When initializing a jsstr_inline_t with a len < 3, the size passed for the allocation is smaller then the size of the structure (as the later is rounded up to the alignment = 4 bytes). GCC 12.2 complains about this when dereferencing the pointer to the structure as the size passed for allocation is smaller than the size of the structure. The warning is fixed by using flexible array member in jsstr_inline_t. Given the rounding behavior in memory allocation, this should not change the size of allocated blocks.
