syscalls/fallocate05: minor fix for Werror=format-security

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.
