Modify gen_init_cpio so that lines that specify files can contain
what looks like a shell variable that's expanded during processing.
For example:
file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0
given RFS_BASE is "/some/directory" in the environment
would be expanded to
file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0
If several environment variables appear in a line, they are all expanded
with processing happening from left to right.
Undefined variables expand to a null string.
Syntax errors stop processing, letting the existing error handling
show the user offending line.
This patch helps embedded folks who frequently create several
RFS directories and then switch between them as they're tuning
an initramfs.
