example/ivy/android: use escapeHtmlTags in ivy output processing

Android App emulates terminal-like functionality in WebView by
appending the input and output lines of Ivy to the WebView HTML
document as a new div entry using javascript. The app used
Android's TextUtils.htmlEncode to get HTML escaped representation
of the input and output. Among those escaped characters, `&` is
included (HTML entity prefix).

Ivy's mobile.Eval returns lines that include HTML entities (e.g.
&#92; instead of backslash -- see
https://github.com/robpike/ivy/blob/master/mobile/mobile.go#L43)
TextUtils.htmlEncode escapes this `&` and as a result, the backslash
is left broken.

escapeHtmlTags is identical to TextUtils.htmlEncode except it
leaves the entity alone.
