[PATCH 1/2] www: call curl with -d '' in the altid instructions

[Kyle Meyer <kyle@kyleam.com>]

Nginx doesn't appear to be happy with just -XPOST, so use -d '' to
avoid potential confusion about why the instructions aren't working.

cf. commit 533e1234bc03a1ca8754d249aa8c2ce157e26780
    (lei_xsearch: use curl -d '' for nginx compatibility, 2021-01-24)
