Skip hbreak-unmapped.exp if memory at address 0 is readable
hbreak-unmapped.exp assumes that memory at address 0 is unmapped or
unreadable, but on bare metal or uclinux targets, memory at address
0 is readable. For example, on arm-none-eabi, the vector table base
address is 0x0.

This patch is to check whether address 0 is readable via command 'x 0'.
If it is, skip the test.
