package/libsoil: fix build using old versions of patch

Well-formed patch fails to apply
- patch v2.6:
Hunk #1 FAILED at 1.
Hunk #2 FAILED at 23.
- patch v2.6.1:
can't find file to patch at input line 11
Perhaps you used the wrong -p or --strip option?
[snip]
No file to patch.  Skipping patch.
2 out of 2 hunks ignored
Patch failed!  Please fix 0001-fix-makefile.patch!

Old versions of the tool "patch" cannot handle spaces in filenames.
The same does not occur using "patch" v2.7 or any later.

Workaround: when a file with space in the name needs to be patched,
one or two hooks must be used.
A pre-patch or post-extract hook renames the file to replace spaces
with underscores.
The patch file must be generated using diff between two source-trees
that have the file renamed with spaces replaced by underscores.
A post-patch hook could rename the file to its original name if needed.
