scheme1: bump READBUF_CAP_BYTES 256 KiB -> 1 MiB

cc.scm crossed ~239 KB at the struct-return commits, pushing the
catm'd prelude+cc.scm+driver inputs over the 256 KiB cap and breaking
cc-lex/cc-pp pipeline fixtures with "source buffer overflow". Total
bss is still well under the 128 MiB p_memsz reservation.
