PATCH v4 1/1 fs: allow filesystems to set the name of their output file

From: Carlos Santos <[email protected]>

Some filesystems may want to tweak their output names, rather than using the fixed "rootfs.foo" scheme. Add a ROOTFS_FOO_IMAGE_NAME variable for this purpose.

---
Changes v3 -> v4 (Yann):
- fix use of $(strip)
Changes v2->v3 (Carlos):
- Fix typo and use strip instead of qstrip, as spotted by Yann Morin.
Changes v1->v2 (Carlos):
- Prevent leading space when the filesystem gets 'imaginative', as pointed by Yann Morin.
