lib/igt_edid: Allocate raw 8-bytes for VSDB

hdmi_vsdb is an element of cea_vsdb which makes the size of cea_vsdb to
be 8 ( 3bytes ieee_oui ) + ( 5bytes hdmi_vsdb struct), its true that we
only use 7 bytes technically we can only allocate 7byte array but since
we are writing to elements of hdmi_vsdb struct which is sitting at offet
4-8 in cea_vsdb, compiler thinks we have an element which is out of
array bounds since out allocated size is 7bytes

This errors out
../git/lib/igt_edid.c:365:13: error: array subscript 'struct hdmi_vsdb[0]' is partly outside array bounds of 'char[7]' [-Werror=array-bounds]
  365 |         hdmi->src_phy_addr[0] = 0x10;
      |             ^~

allocating one extra byte matches with size of cea_vsdb and compiler is
happy
