Summary:
- I noticed that adb shell failed when sh is spawned.
- Finally, I found that an error happened when executing dup2() action
if the file descriptor has the O_CLOEXEC option.
- This commit fixes this issue by dropping the option in the API.
Impact:
- posix_spawn_file_actions_adddup2() only
Testing:
- adbd with sabre-6quad:netnsh (will be merged later)

libc: Fix getrandom() bug: Didn't propagate read error
...
* libs/libc/misc/lib_getrandom.c, in function getrandom():
We were assigning the return value of _NX_READ() to nbytes, a
variable of the unsigned type size_t. Note that _NX_READ() resolves
to either read() or nx_read(), both of which return the signed type
ssize_t to indicate either the number of bytes read successfully
(>= 0) or an error (< 0). Then we were testing for a negative
size_t value, a condition that can never occur. The end result is
that if an error occured in _NX_READ(), it would never be detected
and getrandom() would return some large positive value. This bug is
corrected by assigning the return value of _NX_READ() to a new local
variable, ret, of size ssize_t.

The jump instruction relocation had an assert that tests for jumps with

assert because the jump instruction points to the same address, which

Addend was not handled correctly in several reloc types.
Add ADD32/64 + SUB32/64 relocations, for some reason the compiler
I use likes to add them.
