[PATCH v2] dev-manual: disk-space: improve wording for obsolete sstate cache files

[michael.opdenacker]

From: Michael Opdenacker <michael.opdenacker@bootlin.com>

Replace "duplicate" by "obsolete", more appropriate.
"duplicate" probably comes from the "--remove-duplicated"
option of the sstate-cache-management.sh script.

Improve other sentences too.
