Revert "sys-apps/accountsservice: version bump to 0.6.54"

This reverts commit 844671a9cc203605d9940fd62a826bd5864b9340.

Fails to install any real files whatsoever due to bugs in meson
ebuild port.
Adds questionable keepdir when the idea is to check if pre-existing
dirs are needed at all instead. The keepdir is with wrong path as well.
Keeps deps only possibly relevant to autotools based builds.
