[LTP] [PATCH v2 1/1] Makefile: set LC_{COLLATE, NUMERIC}=C, unexport LC_ALL

[Petr Vorel]

to have reproducible builds (no locale dependencies).
Get inspiration from Linux kernel, commits:
c051346b7db2 ("Makefile: set LC_CTYPE, LC_COLLATE, LC_NUMERIC to C")
07105202bdeb ("Makefile: do not override LC_CTYPE")

NOTE: we don't care about messages not being localized.
