sys.mk: fix duplicate character in character class of LINTFLAGS
The character class contained two times U+0020, which makes one of them redundant, so remove the character class. PR toolchain/18248 already contained these two spaces. Apparently there is no need to support tabs in this place, otherwise someone would have noticed it in the 17 years since this pattern had been added in sys.mk 1.83 from 2004-01-27. No functional change.
