David Disseldorp 7be37c94da initramfs: allocate heap buffers together

header_buf, symlink_buf and name_buf all share the same lifecycle so
needn't be allocated / freed separately. This change leads to a minor
reduction in .text size:

before:
   text    data     bss     dec     hex filename
   7914    1110       8    9032    2348 init/initramfs.o

after:
   text    data     bss     dec     hex filename
   7854    1110       8    8972    230c init/initramfs.o

A previous iteration of this patch reused a single buffer instead of
three, given that buffer use is state-sequential (GotHeader, GotName,
GotSymlink). However, the slight decrease in heap use during early boot
isn't really worth the extra review complexity.
