Previously, if `cpio_vec_insert()` needed to replace a file and the file
already exists as the first entry, then a duplicate entry would get
created.
This fixes the bug I reported at:

Some functions, like `patch_init_rc()`, treat buffers read into memory
as a string instead of a byte buffer. Since the buffers weren't
NULL-terminated, this resulted in out-of-bounds reads and caused crashes
in certain conditions.
THis commit updates fd_full_read() to always NULL-terminate the buffers
so that they can be treated as strings when working with text files.

When both keepverity and keepforceencrypt are false, ‘e’ will be freed after removing ‘verity_key’ and segmentation fault might happened in strstr(e->filename, “fstab”)

For certain device (e.g ZenFone 4 ZE554KL) there’s no sepolicy under rootfs and no a/b partition (implies no vendor partition) Magisk will failed to patch SELinux policy database and the system won’t boot up.
In order to cope with this configuration the status of loading policy db needs to be checked, once it failed we have to mount the system partition and do patch_sepolicy() again.
