In order to avoid compilation issues in tst_XXX functions:

gcc -g -O0 -fdebug-prefix-map=. -fstack-protector-strong -Wformat
-Werror=format-security-g -O2 -fno-strict-aliasing -pipe -Wall -W
-Wold-style-definition -Wdate-time -I../../../../include
-I../../../../include -I../../../../include/old/ -Wl,-z,relro
-L../../../../lib  fallocate05.c -lltp -o fallocate05
fallocate05.c: In function ‘run’:

fallocate05.c:76:4: error: format not a string literal and
	no format arguments [-Werror=format-security]
    tst_brk(TCONF, tested_flags);
    ^~~~~~~
fallocate05.c:78:3: error: format not a string literal and
	no format arguments [-Werror=format-security]
   tst_brk(TBROK | TERRNO, tested_flags);
   ^~~~~~~
fallocate05.c:80:2: error: format not a string literal and
	no format arguments [-Werror=format-security]
  tst_res(TPASS, tested_flags);

when using format-security, change "const char *" to a
pre-defined string.
