Expanders in Site options are all ARIA-expanded by default

[Jono M]

In 15.10, the sections in Site options (/admin/site/options.php) use new Bootstrap expanders, with the ARIA-expanded attribute added for accessibility. However, on page load all the expanders have the attribute aria-expanded="1" despite being collapsed by default. This needs to be changed to aria-expanded="false" or equivalent.

Fix aria-expanded attribute on pieforms fieldsets (Bug #1484779)

The attribute was being set in reverse (1 for collapsed, 0 for
expanded) so I've made it more explicit. Note this also fixes
various other pages (eg. "Settings" in "Add group") as well as the
reported bug
