[Tile-serving] [openstreetmap/osm2pgsql] Wrong the rule of thumb in slim mode (#1433)

[Valerij Ivashchenko]

Also I found that there is a little inconsistent information about --slim mode and required cache size.

In [8.3 Caching](https://osm2pgsql.org/doc/manual.html#caching) section:
```
 The rule of thumb in slim mode is as follows: use the size of the PBF file you are trying to import or about 75% of RAM, whatever is smaller.
```

In [8.5 Middle Command Line Options](https://osm2pgsql.org/doc/manual.html#middle-command-line-options) section:
```
 As a rule of thumb, give a bit more than the size of the import file in PBF format.
```
