Fix meson warnings

As written, when we pull in the boost and boost-url subprojects, we hit
problems in the meson files.

```
../meson.build:291: WARNING: include_directories sandbox violation!
```
This commit resolves this issue, by adding explicit meson.build files
for both boost and boost-url.

Tested:
meson buildlocal

No longer returns the above error, and shows
  Subprojects
    boost                                 : YES
    boost-url                             : YES

Whereas previously those two dependencies showed up as NO.

Code compiles.
