PaulW cfe876cefb Update backuptool.sh to correctly process force_backuptool flag/file.
This is regarding the following patch:
5cdb4ec653

The patch which was to allow custom_backup_list.txt to be maintained while flashing via ROMManager
WHILE the flag/file force_backuptool is set/present still has issues.  There are 2 reasons for this.

1) The flag is only checked during the first pass (backuptool.sh backup), as once /etc/force_backuptool
   is known to exist, all files are moved to /tmp/backupdir as designated, but when the script is
   ran again once /system has been wiped and updated, the file /etc/force_backuptool no longer exists
   as it was moved to /tmp/backupdir/force_backuptool, so the script fails as it is not checking that
   location.

2) When the backuptool.sh script is called, the above function (checking for force_backuptool) is called
   *before* the /system partition is mounted.  This therefor ignores the file regardless of whether it
   exists or not.  This is caused by check_installscript being called at the wrong point of the script.

There are therefor 2(two) main changes to this script to allow the force_backuptool override to work.
The first being within the main function of check_installscript, and the second being the location of
where check_installscript is called (ie, I moved it to below check_prereq call in the case statement,
as mounting is called before the check_prereq function checks if the ROM version is the same).

This affects *all* devices.
