Remove box-shadow overrides causing unintended flat headerbar buttons.

Removing the "box-shadow: none;" overrides in adapta.css allows buttons
to use box-shadows when set by more specific rules (e.g. the styles for
headerbar buttons). As the default is to not have a box-shadow this
should not change any buttons that have not had box-shadows explicitly added.

This fixes 'flatening' during hover on headerbar buttons as headerbar
buttons have box-shadows explicitly enabled.
