Revert "Enable DMP for system Chromium WebView on Android"

This reverts commit a2f57e2cbfffa257ef542aa44807ee5d616cd15d.
(http://crrev.com/18314006)

Reason for the revert: it is not being actively used anymore, since
having tcmalloc in libwebviewchromium.so doens't help with allocations
from other libraries like system skia.
Also, some work on the android_use_tcmalloc is ongoing and this dead code
is adding unnecessary maintaining effort.
