Themes: Fix -110 install error [1/2]

aapt was being called from PM with a ' ' at the end of the cmd. This would
cause installd to read unexpected parts of memory which sometimes
causes it to parse the command incorrectly.

Avoid calling idmap w/ trailing whitespace [2/2]

installd performs a buffer over-read if trailing ws is sent to it.
No observable effect found yet for idmap, but until installd is
fixed upstream, best to play it safe.
