Correct installable address whitelist (#816)

* Correct installable address whitelist

blacklist is stored at 0xb088~0xb0bf, which is ulong[14] in
{start(inclusive), end(exclusive)} pair.
one thing to note is that boot9 use inclusive comparing with
blacklist start for both section load address and
section load address + section size (comparing logic is
at 0xa42e~0xa449), so if the firm fits perfectly at the end
of the space right before the blacklisted range,
it'll also be rejected.

* shrink vram drive size to avoid bleeding into blacklisted range

 You may run `make release` to get a nice, release-ready package of all required files. To build __SafeMode9__ (a bricksafe variant of GodMode9, with limited write permissions) instead of GodMode9, compile with `make FLAVOR=SafeMode9`. To switch screens, compile with `make SWITCH_SCREENS=1`. For additional customization, you may choose the internal font by replacing `font_default.frf` inside the `data` directory. You may also hardcode the brightness via `make FIXED_BRIGHTNESS=x`, whereas `x` is a value between 0...15.
 
-Further customization is possible by hardcoding `aeskeydb.bin` (just put the file into the `data` folder when compiling). All files put into the `data` folder will turn up in the `V:` drive, but keep in mind there's a hard 256KiB limit for all files inside, including overhead. A standalone script runner is compiled by providing `autorun.gm9` (again, in the `data` folder) and building with `make SCRIPT_RUNNER=1`. There's more possibility for customization, read the Makefiles to learn more.

 To build a .firm signed with SPI boot keys (for ntrboot and the like), run `make NTRBOOT=1`. You may need to rename the output files if the ntrboot installer you use uses hardcoded filenames. Some features such as boot9 / boot11 access are not currently available from the ntrboot environment.
