[eglib] Fix compilation on PLATFORM_ANDROID.
Compilation of eglib/src/goutput.c was broken in commit
989165e1:
mono/eglib/src/goutput.c: In function 'monoeg_log_default_handler':
mono/eglib/src/goutput.c:159:75: error: 'args' undeclared (first use in this function)
__android_log_vprint (to_android_priority (log_level), log_domain, "%s", args);
^
mono/eglib/src/goutput.c:159:75: note: each undeclared identifier is reported only once for each function it appears in
mono/eglib/src/goutput.c: In function 'default_stdout_handler':
mono/eglib/src/goutput.c:168:2: error: incompatible type for argument 4 of '__android_log_vprint'
__android_log_vprint (ANDROID_LOG_ERROR, "mono", "%s", message);

mono/eglib/src/goutput.c: In function 'default_stderr_handler':
mono/eglib/src/goutput.c:175:2: error: incompatible type for argument 4 of '__android_log_vprint'
__android_log_vprint (ANDROID_LOG_ERROR, "mono", "%s", message);

(The cause of the breakage is that __android_log_vprint() takes a
va_args parameter, which is no longer present in
989165e1.)
Use __android_log_write() instead of __android_log_vprint().
Note: __android_log_write() writes a "simple string" to `adb logcat`,
meaning there is no printf(3)-style formatting applied.
