stdlib: increase number of static atexit handlers to 32
The existing limit of 20 was found to be insufficient when moving from
gcc 8 to gcc 9. At the time a test ran already 16 handlers had been
installed leaving only minimal room for application installed handlers.
Musl uses 32, as does newlib. Further, the ISO C standard for C99
specifies that:
The implementation shall support the registration of at least
32 functions.
(7.20.4.2 The atexit function)
