util: Don't use "\e"

Browse Source 
'\e' representing ESC (0x1b) is not C standard, it's an GNU extension.

Since the code also compiles on Windows with Microsoft compiler, we
should use '\033' instead.

Note: I didn't try to build the whole wpa_supplicant on Windows, so I
don't know if it still builds (I have no Visual Studio 2005 for a quick
test). I just needed the string conversion routines for the P"" syntax
in both directions.
