libdwfl: read_address should use increasing address in intuit_kernel_bounds
In kernels from 4.14 up to 4.19 in /proc/kallsyms there are special
__entry_SYSCALL_64_trampoline symbols. The problem is that they come
after the last kernel address, but before the module addresses.
And they are (much) smaller than the start address we found. This
confuses intuit_kernel_bounds and makes it fail.
Make sure to check read_address returns an increasing address when
searching for the end.
