docs/manual: standardize a bit more the formatting of commit titles

Currently, our commit titles are not very well standardized, and it
would be great to standardize them a little bit more. A number of
people use "<pkg>: " as prefix, others use "package/<pkg>: ". Some
people start the rest of the commit title (after the prefix) with an
upper-case letter, some with a lower-case letter.

In an attempt to standardize this, this commit updates the manual with
some examples of good commit titles.

First of all, it is essential that the patch has a good commit
message. The commit message should start with a separate line with a
brief summary of the change, starting with the name of the affected
package. The body of the commit message should describe _why_ this
brief summary of the change, prefixed by the area touched by the
patch. A few examples of good commit titles:
* +package/linuxptp: bump version to 2.0+
* +configs/imx23evk: bump Linux version to 4.19+
* +package/pkg-generic: postpone evaluation of dependency conditions+
* +boot/uboot: needs host-{flex,bison}+
* +support/testing: add python-ubjson tests+
The description that follows the prefix should start with a lower case
letter (i.e "bump", "needs", "postpone", "add" in the above examples).
Second, the body of the commit message should describe _why_ this
change is needed, and if necessary also give details about _how_ it
was done. When writing the commit message, think of how the reviewers
will read it, but also think about how you will read it when you look
at this change again a few years down the line.
Second, the patch itself should do only one change, but do it
Third, the patch itself should do only one change, but do it
completely. Two unrelated or weakly related changes should usually be
done in two separate patches. This usually means that a patch affects
only a single package. If several changes are related, it is often
