Add backslashes to "Adreno (TM) 3xx" canvas/ganesh whitelist entry.

Add backslashes to "Adreno (TM) 3xx" canvas/ganesh whitelist entry.

This entry didn't match because the parens were interpreted as regexp
grouping instead of literal characters.  I didn't notice the problem
before given that K+ Adreno 3xx devices are also covered by the OpenGL ES
3.0 policy.  This should actually expand the Ganesh whitelist to all pre-K
Adreno 3xx devices as originally intended by r307526.

PTAL.  Another string matching problem, somewhat embarrassing :/  This means 41
went out without the Ganesh device expansion I had intended, unfortunately.

I think as this is a C++ file, there should be "\\" two back slashes to
represent a single slash.

See for example "gl_vendor": "X\\.Org.*",

Empirically, this patch works on a Jellybean Adreno Nexus 7 (and doubling the
backslash also works).  It uses "#define LONG_STRING_CONST(...) #__VA_ARGS__",
not regular C++ strings.  http://en.cppreference.com/w/cpp/preprocessor/replace
says in that case "In addition, the preprocessor adds backslashes to escape the
quotes surrounding embedded string literals, if any, and doubles the backslashes
within the string as necessary.".

Well, GpuBlacklistTest.CurrentBlacklistValidation didn't like the single
backslash, so I switched to the two backslashes.  PTAL
