init: Fix get_hardware_name() to cope with long /proc/cpuinfo output

get_hardware_name() uses a fixed size buffer to slurp the contents of
/proc/cpuinfo into and with newer multicore systems this is not big
enough, leading to the inability to pick up the hardware name.

Fix this by using a dynamically allocated, exponentially growing buffer.

Cleanup fs_getline from fs_mgr

Since getline is included in bionic, fs_mgr can use this version instead of
the one defined internally by fs_getline.

Replace fs_getline with getline.

Fix fstab memory leak

When reading the fstab config file fails, fstab memory is not freed.
When fstab structure is no longer needed, only half of it is freed.

Free fstab memory in all cases (error or when it is no longer needed).
