[PATCH v1] Use pthread_kill instead of pthread_cancel for compatibility

[Kelvin Zhang]

pthread_kill is supported on more platforms. For example, android's
bionic libc does not have pthread_cancel. Since pthread_setcancelstate()
is not used in erofs-utils workqueue code, pthread_cancel has identical
behavior to pthread_kill, this switch should be safe.
