libretiny: fix RTL8710B linker regex — output is .ram_image2.text not .image2.ram.text

Browse Source 
Confused the output section name with the input glob. RTL8710B's linker
template has:

  .ram_image2.text : {
    KEEP(*(.image2.ram.text*))
  } > BD_RAM

so we need to match ".ram_image2.text :" and inject our extra
KEEP(*(.sram.text*)) alongside the existing input glob. CI caught this;
the test_build_components rtl87xx-ard smoke test now exercises the
patcher.
