MDL-56511 theme_boost: Work around CSS Parser restrictions

Browse Source 
The CSS Parser used in Moodle does not handle the use of complex
calculations at this stage.
The temporary workaround here uses a fixed position to ensure that the
popover arrows affected are in the correct location.

/* Force positioning of popover arrows.
*
* The Css prefixer used in Moodle does not support complex calc statements used
* in Bootstrap 4 CSS. For example:
* calc((0.5rem + 1px) * -1); is stripped out by lib/php-css-parser/Parser.php.
* See MDL-61879. For now the arrow positions of popovers are fixed until this is resolved.
