It was possible for the Hotspot 2.0 case of OSU user interaction to fail
with wpadebug browser due to permission denial in the "start" command
("java.lang.SecurityException: Permission Denial: startActivity asks to
run as user -2 but is calling from user 0; this requires
android.permission.INTERACT_ACROSS_USERS_FULL"). Avoid this by using
more flexible USER_CURRENT_OR_SELF (-3) value with the --user argument.

This converts most of the remaining perror() and printf() calls from
hostapd and wpa_supplicant to use wpa_printf().

This allows the URL to be passed as a single argument to the program
instead of getting split into multiple by os_exec(). This makes the
operation more robust for cases where the URL could have been received
from an external source and could potentially add extra arguments to the
command line.

Use os_exec() to run the external browser to avoid undesired command
line processing for control interface event strings. Previously, it
could have been possible for some of the event strings to include
unsanitized data which is not suitable for system() use.
