libre/iceweasel: Update to 81.0-2.parabola1

Setting MOZ_APP_NAME is necessary now because paths to binaries will
contain 'firefox' not 'iceweasel' due to changes in this release of
upstream Firefox.

+Subject: [PATCH] Bug 1660901 - ignore AT_NO_AUTOMOUNT in fstatat system call.
+ r=jld
+
+Per the manpage "Both stat() and lstat() act as though AT_NO_AUTOMOUNT
+was set.", so don't bail if it's set in a call to fstatat.
