Change remaining Android logging macros to use C99 varidaic syntax

Most of the system/core/include/log/log.h file uses the C99 syntax of
variadic macros (that is, '...' in parameter list and __VA_ARGS__
in arguments). Except for andoid_printLog and android_printAssert
which still uses GCC custom extension syntax.

Switched the remaining macros to use C99 syntax. GCC extension syntax
makes my editor's code parser puke.

BUG: None
