Make "Detecting a potential buffer overflow" example more uniform

jketema · jketema · commit eb6c8480f838 · 2023-02-22T10:02:12.000+01:00
All queries that use SSA import `semmle.code.cpp.controlflow.SSA` explicitly,
except for the last one. Also import the library there. Note that this is not
strictly necessary, as the library is transitively imported via `import cpp`.
