samples/bpf: Fix passing LDFLAGS to libbpf
samples/bpf/Makefile passes LDFLAGS=$(TPROGS_LDFLAGS) to libbpf build
without surrounding quotes, which may cause compilation errors when
passing custom TPROGS_USER_LDFLAGS.
For example:
$ make -C samples/bpf/ TPROGS_USER_LDFLAGS="-Wl,--as-needed -specs=/usr/lib/gcc/x86_64-redhat-linux/13/libsanitizer.spec"
make: Entering directory './samples/bpf'
make -C ../../ M=./samples/bpf BPF_SAMPLES_PATH=./samples/bpf
make[1]: Entering directory '.'
make -C ./samples/bpf/../../tools/lib/bpf RM='rm -rf' EXTRA_CFLAGS="-Wall -O2 -Wmissing-prototypes -Wstrict-prototypes -I./usr/include -I./tools/testing/selftests/bpf/ -I./samples/bpf/libbpf/include -I./tools/include -I./tools/perf -I./tools/lib -DHAVE_ATTR_TEST=0" \
LDFLAGS=-Wl,--as-needed -specs=/usr/lib/gcc/x86_64-redhat-linux/13/libsanitizer.spec srctree=./samples/bpf/../../ \
O= OUTPUT=./samples/bpf/libbpf/ DESTDIR=./samples/bpf/libbpf prefix= \
./samples/bpf/libbpf/libbpf.a install_headers
make: invalid option -- 'c'
make: invalid option -- '='
make: invalid option -- '/'
make: invalid option -- 'u'
make: invalid option -- '/'
[...]
Fix the error by properly quoting $(TPROGS_LDFLAGS).
