buildtools: fix build with coverage
A compiler can reuse a variable name and prefix it when instrumenting
with coverage.
Example:
$ make defconfig T=x86_64-native-linux-gcc O=master
$ make EXTRA_CFLAGS='--coverage' O=master
[...]
CC rte_flow.o
rte_flow_dynf_metadata_offs is not flagged as experimental but is listed
in version map
Please add __rte_experimental to the definition of
rte_flow_dynf_metadata_offs
$ objdump -t master/build/lib/librte_ethdev/rte_flow.o |grep _offs$
0000000000000000 l F .text.startup 000000000000000a
_GLOBAL__sub_I_65535_0_rte_flow_dynf_metadata_offs
0000000000000620 g O .data 0000000000000004
rte_flow_dynf_metadata_offs
Protect against this by adding a space character in the pattern.
