package/memstat: update the patches to be applied with fuzz 0

Commit 8f88a644ed7d6 ("support/scripts/apply-patches.sh: set the maximum
fuzz factor to 0") reduced the fuzz factor.

Due to this change, memstat fails to build with output:

    Applying 0001-PATH_MAX.patch using patch:
    patching file memstat.c
    Hunk #1 FAILED at 19.
    1 out of 1 hunk FAILED -- saving rejects to file memstat.c.rej

This commit refreshes the package patch on the current package version.
