[aur-dev] [PATCH] pkgfuncs.inc.php: Avoid printing duplicates in "Required by"

[canyonknight]

Packages with multiple DepConditions are returned multiple
times in the "Required by" column.

Array is multi-dimensional so cannot have array_unique() run over
it directly to remove duplicates. Serialize the array, remove
duplicates, then unserialize the array.

Fixes FS#32478
