File name too long when caching files

Hello.

I love your project and would like trying to port Motorola Moto G 2014 (titan).

However the first problem that I found it when running pmbootstrap.py checksum device-motorola-titan.

vermuth:~/src/pmbootstrap[master*]$ ./pmbootstrap.py checksum device-motorola-titan

I'm using ecryptfs but not sure if that is the cause. Here is the workaround I did: https://github.com/PabloCastellano/pmbootstrap/commit/40e5ba651daf0207f45f237eeecb6883c8e8bdb2 Feel free to cherry-pick it
